I love how flowey basically went “I DID NOT WATCH YOU LIVE WITH TORIEL 20 TIMES AND THEN TAMPER WITH SWITCHES JUST FOR YOU TO DO THAT ALL OVER AGAIN”

The tutu and ballet shoes are also hidden behind a waterfall and in a patch of grass (or whatever it is in waterfall), which lines up with Axis having "hid the evidence"

7:28 I really hope they keep this typo in. Axis boasting about being smart and making a minor spelling mistake is really amusing.

Oh, so thats why Ceroba gets mad at Clover when they kill Axis in Pacifist. Its because they de-purified their heart by killing. Ceroba called off the mission immediately, as she then knew clover's soul was pointless.

23:10 Y’know, Chujin being disturbed to the point of not sleeping makes a lot of sense considering monsters just turn to dust when they die, they don’t ever really see corpses (expect maybe when a monster had fallen down that might be comparable to a corpse)

I love how the game resetting the moment Clover climbs up the rope to Toriel perfectly lines up about what we learned in the neutral route - Flowey realized that Clover was headed to a dead end for him by staying with Toriel again, so he reset before that happened

Ive been doing back-to-back neutral runs and Flowey starts to have some interestung dialogue after a while. Also, he gets quite annoyed if you refuse to save

the random soul found in waterfall makes a lot more sense after you hear Axis dialogue in a genocide route basically saying Axis merced the kid and hid the evidence of the killing which includes the soul, the shoes, and tutu hidden in obscure places within waterfall

The Macro Froggit was truly the most epic boss I have ever seen no wonder it was hidden especially the wonderful Final Frog towards the end.

I love how chat immediatly started using Marlet's emoticons as soon as they appeared ^v^

In the rope ending, when it glitches you can see a tiny flowey at the top left

this game follows the cannon so closely that I feel like it'll be hard to not subconsciously misremember details from this game as actual lore in the future😂

I'll be honest I never even realized many people consider the blue soul to have killed. I just thought that the tutu and shoes may have been dusty because they've been left behind for a long time (especially since they're in very hidden places that can be easily skipped over). But then it hit me, the green soul's items (stained apron and the frying pan) are also items you can collect in the overworld, same with cyan soul's items with the toy knife and ribbon. None of those items are described to be dusty whatsoever. The apron and frying pan I get, after all there's no way a human with a kindness soul would hurt a monster (which makes me wonder what would happen if they even attempted a genocide run, would their soul even be able to handle it?). As for the ribbon and toy knife I'll admit, I didn't get it but thinking further I can understand, patience is all about waiting for to achieve what you want, so perhaps the cyan soul child was patient enough to understand the monsters and not jump into combat immediately. TBH I'm honestly shocked at this revelation, as integrity represents the quality of being honest and having strong moral principles. Maybe because of the moral principles the blue soul felt justified in their kills? Idk but another soul I initially thought was the one axis killed was the purple soul, which you can tell by the fact the state of its corresponding equipment (glasses are cloudy, probably due to dust, and the notebook is torn which as someone with a ton of notebooks I can confirm that that notebook must've been through some stuff to be that worn out). Idk why this is all interesting to me but it is. TLDR: I learned about some sweet possible Undertale lore I never knew about before.

6:12 that rabbit is the most powerful NPC in the game because they can just walk through a solid wall

Yellow managed to satisfy my soul's deepest desire for new Undertale content

0:35 Imagine if there was a whole route you could play after climbing the rope 😭

Integrity Demise Timeline: 17:40|23:06 • The child with the Integrity SOUL falls into the Underground • They proceed to do a Neutral run (or an ongoing genocide run, we don't really know, the most info we get on their actions is that they have indeed hurt some monsters, Chujin himself witnessed it) • Chujin activates Axis and ran a protocol that made him chase the child into Waterfall to "apprehend" them • Axis proceeds to completely obliterate the child using his lasers, much to Chujin's horror after arriving shortly to the murder scene • Afraid of anyone finding out, Axis "hid the evidence" in Waterfall (probably by order of Chujin) shortly after "containing the subject" (which I assume is the soul, otherwise the only other thing to contain is the body, and I hope Chujin didn't just pull a FNAF on us with the dead kid and the robot and what not, though wouldn't that explain why killing Axis gives you EXP? Whatever...). This lines up in the actual canon lore, that's why we find their ballet shoes and tutu hidden in a patch of grass in OG Undertale • Chujin keeps the blue soul for awhile to experiment on, mostly on himself using the serum (but also maybe on Axis aswell?). • After "years" have passed (as mentioned in the book in the Steamworks office secret room), Chujin (or maybe Ceroba) dumps the blue soul back into Waterfall which was then discovered by one of the Royal Guards and sent straight to Asgore's castle for safekeeping This timeline explains how Chujin was able to use a Soul to create his serums whilst also having Integrity be in one of Asgore's capsules by the time Clover fell down into the Underground

it's so cool how you need to find secrets in both pacifist and neutral, AND play geno to piece together the fate of the blue fallen human from all perspectives. chujin's programming mistakes "forced" axis to kill the human before quickly hiding the evidence (hence why the tutu and ballet shoes are hidden in undertale), and chujin took the soul to make the serum out of it; when it failed because the human was impure, chujin deemed the soul useless for his endeavors and left it in waterfall to avoid suspicion, where it was then discovered and brought to asgore

The reason why your name is clover is because in the omega flowey fight when you get to the yellow soul part the gun starts shooting clovers at you when it starts trying to heal you

Fun fact! If you go to the Golden Coffee area without encountering Micro Froggit, there won't be anyone in the mini pool. The text for checking it will be different too. The coffee will be there though. I found it by accident on my first playthrough and thought it was for the guy stuck to the pole, buuuut it wasn't.

Its crazy that a fangame is getting so much attention

the fact that flowey just full resets the game because he wants you to not go back with toriel is so funny to me

Dammit, I *need* to see where this can go. We need Undertale Cyan, Orange, Blue, Purple and Green. Even if it takes 15 years.

we will definitely need WAY more updates to this video in the future since yellow has only been out for a few days and a TON of new stuff is probably being discovered every day :3

9:39 Finally, Shayy is in a fangame as a boss.

god the way they even expanded on the other humans' lore too. I never evn thought of Integrity to be the killing type after people rementioned that the ballet shoes were dewcribed as dangerous and how the old tutu was referred by papyrus as a "dusty tutu" because they interpeted it as if the blue soul did a lot of killing. Also considering how the shoes were also a really strong weapon too. God i love it

Man this game was absolutely amazing. Deltarune level quality, and far beyond. And yes, it took them 7 years, but the wait was 100% worth it. I hope their next project, even if most likely not undertale related, will be just as good. Also, thousands of hours of work for FREE. Mind boggling. Quick edit, make sure to support the creators other works as well. The best way to show appreciation!

The monster in the Steamworks can actully be encountered sort of in Genocide, if you interact with the room's "door" it says you can't open it, but someone is trembling behind it. I assumed it was robots, but I guess not.

Shayy finally fights the dead pixel that's been plaguing his boss fights for years

In my genocide route, I am unsure what triggered it but, I left the room where you get the ice bullets and entered a secret room with a girl in the center. The music turned off, the whole room had trees on the edges, and I went by her dialogue too quickly and she then repeat another line. I forgot it and didn't think to record it but I'm not lying, somebody please confirm this if you ran into it, or try to trigger it.

25:09 It also leads me to believe that this is why the serum worked on Martlett during the genocide route, because Martlett wanted to stop Clover's genocide once and for all, and since we know now that the blue soul child has killed monsters beforehand, making their soul not pure, this is why the serum didnt fail on Martlett's body during the genocide route. Although it's not confirmed whether Martlett has a boss monster soul or has the soul of an average monster, l believe Martlett has the soul of an average monster because of this: Remember how during the 2nd flashback in Ceroba's memory (in the pacifist route), that it showed once serum was injected into Kanako, that it had failed horribly? Well, Chujin said in one of the tapes that Kanako is a boss monster. Chujin also states that when he conducted more tests on serum, that the substance rejected the fusion, which led to the deterioration of his soul. Both Chujin and Kanako are boss monsters, and it seems that the serum failed on both monsters who had the boss monster gene. However, nothing was said about serum working on an average monster soul. Chujin said in one of the tapes that a serum would transform any AVERAGE monster. (This was where after, he had to conduct more tests on serum) But he conducted the tests on himself, a boss monster soul, not an average monster soul. Due to Martlett's intent to kill clover, which combined with the purelessness from the integrity soul, this is why the serum worked on Martlett, having the intent to kill at that moment allowed Martlett to transform into a boss monster.... and then the final fight begins... This might be a little far-fetched, but let me know how you guys think of it. Edit: I just realized, during Martlet's cutscene before the 2nd phase on genocide, she goes to the True Lab. It was said at one point by Ceroba that Kanako was being kept at the Lab after she had "fallen down" after the serum failed on Kanako during the Pacifist Route. It was likely that when Martlet had entered the Lab, that she discovered what truly happened to Kanako, as well as possibly re-discovering the serum (Which many people presume that this was where Martlet found the serum, and used it during the final battle against Clover).

Something interesting is that you can still get the golden items for the bandana in the Genocide route AND use them for the bandana itself. Except you won't fight Macro Froggit. You'll just instantly be given the chest to open. That bandana is super useful for Zenith Martlet too, as it reduces the damage you take from 11 to 9. It's not a whole lot of course, but it's still helpful to have at least one more hit you can take.

I love how self aware this game is, just like undertale

I can sense the love put into this game. The faith to the original game and persistance on continue making this is absolutely remarkable.

I can see why this game took 7 years to make.

I actually like the fact the plot of this game used the serum as a more precarious and direct way compared to alphys method in the original UT that she used the weeds where Integrity was found. And made Undyne ingest them by eating them, Phonecalls also mention that its part of the ice cream she gets and if you check on alphys' lab you can see the machine that turns said seaweed into ice cream. Explaining how Undyne got human determination powers by doing something similar but Alphys method had her possess stable results (until Undyne gets killed in either neutral or genocide route). So the Serum is a more direct route but unstable that also weilds greater powers. While Alphys method by ingestion seemed to provide lesser but more stable results.

Imagine if we got 5 other fan games of this quality about the other fallen children

people behind this game are incredible for working their ass off so Badly on something they won't be able to get money from

I can see Undertale Blue being a project they have they’re eyes on. Lots of interesting lore set up for it.

Really love these videos you've been releasing, the commentary and reactions make it so much fun to watch

dude just dropped some crazy lore i never knew casually dusty tutus what else could it be

I never realised that the blue soul's Tutu was Dusty of monster ash, i always thought it was just old

I like how macro froggit is disturbed by the mega froggit while the lower face (thing?) is enjoying its body (13:11)

I love how most secret bosses are very important to the storyline/lore, and then undertale yellow is just like *B I G F R O G*

The book of paranormal events references various fun events that can happen, the arcade one refers to one sketchy looking npc that can appear there, the one in snowdin refers to the two secret npcs you can find leaving the frozen pellet room. (it also references axis killing the blue soul ballet kid)

13:30 this is the greatest character in fiction

The robot frog had Flipnote Hatena frog on it. Nice reference for a beloved animation software and website from the Nintendo DSi era

6:20 The random comment of "CELESTE CHAPTER 9??" when the kid went through a wall got me good.

Lore ! Now we must wait for Undertaile Blue, where genocide would be a cannon event.

i love how the micro froggit is classified as a boss because of the special spare effect

I feel proud of myself for finding the secret tape right away. It definitely made things easier to understand after

Also in addition to it being the blue soul, there is a map somewhere I can’t really remember where that shows all of the souls and a dark blue question mark

[neutral ending spoilers] 0:35 the animation implies flowey reset Clover haha "nonoNONONO WHAT ARE YOU DOING YOU'RE SUPPOSED TO G- forget this i'll just [File 1 Deleted]"

Macro’s froggit’s reactions to buff froggit are absolutely fucking priceless 😂

Man, lots of lore surrounding the blue soul specifically. I wonder if the game is trying to imply that Sans and Undyne are so worried about Papyrus’ safety because there have been attacks in Snowdin before.

I KNEW THE GOLDEN ITEMS HAD TO HAVE A BIGGER PURPOSE!!!! I'm gonna replay the game soon anyway so I'll keep this in mind for next time! ^^

0:36 Flowey: NO, I WATCHED THIS HAPPEN TOO MANY GODDAMN TIMES, I'M GONNA FREAKING RESET. I NEED MY SOULS.

Note: The NPC that normally appears in neutral and pacifist that you give the coffee to in exchange for the soggy mitten does not appear in the genocide route. At least, that's the way it appears to me.

if you interact with slurpy as he runs off to go home, it will bring up the menu to use an item to unfreeze his tongue again, even after he's free.

the first one is f*cking hilarous flowey like: OMFG NOT THIS AGAIN

I have never fully realized that "dusty" in dusty tutu means killed monsters by the blue souls human.

I feel like the book in the hidden lab room was talking about the purple soul instead of the blue one. Just because the idea of lying in wait and hiding away sounds more like something the Perseverence trait would fall in line with. Plus, Integrity was described to be on a crusade, and their attacks were pretty well known

I spent the last day watching all three of your video on it and i'm honestly HOOKED!

That's why I love this type of games. Many many secrets, easter eggs, theories, deep minds and many many more!

Man this fangame has a lot of love and effortnput into it, it was worth the 7 years a true great fangame

6:14 fun fact: when the NPC is walking away, you can still interact with him, and the game will act like he’s still stuck to the pole

Man Shayy got lucky having both 10:40 and 11:07’s Macro Froggit attacks be timed to the music

Man if only Alphys had thE BALLS Chujin had to confess her sins, that way many people wouldnt hate Alphys as mutch as they do .( now that think of it.... all mosters in UT yellow apologize after attacking you, something NO ONE did in proper undertale, sans even shushes you and calls you a crybaby when you tell him you´ve previosly been murdered by monsters) Alsoooo...... notice how marlet tore the last enrty of her journal because she got traumatized by the amalgamates, fuck she lied Ceroba at the end of the pacifist run By saying she would open an investigation about Kanako, hadnt she done that..... Ceroba migth just had beaten Alphys to Death with her bare hands. LIKE SHIT! had Ceroba won the figth against Clover she migth´ve just murder Asgore and lost her mind, like Fuck! T H E P L O T D E E P E N S

FUN FACT!! Regarding the Band Merch Pin item, you can actually get it more than once. Which means you can get a TON of money if there's a way to sell items. I forgot if there was, But if so, make sure to keep that in mind.

You might already know this one, it looked like you briefly checked for it in your playthrough but moved on without saying anything- When you go to bits and bites in the genocide route there's a tall, ominous figure standing in the doorway and watching you. Seen people claim they can see it in game, but if you can it's realllly hard to make out. I had to take a screenshot and crank the brightness up 3x in order to see anything but it's definitely there. quite spooky. :)

God the lore in these secrets, its soo dam good n theres more to be fond

kinda-fun-fact: you can see flowey watching you when you're riding Ava. at least. in neutral. i did. dunno. just a small lil detail i thought was p cool.

There is a secret area in the woods in the room where you get the ice bullets. Its a girl who says that she got lost in the woods to get attention from a guy, just to later tell that the guy doesn't exist and how cool would it be if he really existed. Dont quote me on that, but i think her name is jane or something

THEORY ABOUT AXIS'S ORIGINS(SPOILERS) . . . . . Axis is the only robot that gives EXP upon being killed. This means that Axis must have a SOUL, just like Mettaton. Whether it is human or monster is unknown. We find that Axis killed a human and hid the evidence, which could show that the SOUL Axis has was human(although I find this to be less likely). The magic that Axis uses doesn't align with the magic Ceroba uses, and it is unknown if Chujin is capable of using magic. The SOUL cannot be Kanako's for two reasons: 1. Ceroba mentions that she was sent to Alphys's lab, and is now likely an amalgam and 2. Axis was a private project that Ceroba didn't know about until entering the Steamworks with Clover. In the pacifist run, while in the Steamworks with Ceroba, you can find logs of previous Axis models, all of which failed. The current model not only works, but was also capable of feeling emotion, as shown before the final fight with Axis in genocide when explaining his relief that he was able to save a few of the robots. Throughout UT and UTY, monsters are shown to be kind and caring by nature, with only a few having ill intent, while humans can vary much more. As seen in a cutscene during the pacifist Ceroba fight, Chujin is almost immobile, stuck in his bed. This leads me to believe that he was in no shape to get to Axis and transfer his own SOUL into Axis, as Axis was located at the Steamworks. This leads me to believe that the SOUL of an unknown monster was used to make Axis successful.

16:00 funfact, when i played the game for the first time i wanted to interact with the shelves for items until i found this guy, i didn't even know it was a secret 😭

Good job, I really enjoy your videos keep up champ

I found a secret! Don't know anything about it but when i left the room where the ice falls off the tree and you get the ice pellet ammo, Instead of going back to the normal area, I went into a room with no music and a unicorn. She says "Did Mikey send you?" "Huh?" "Huh??" "Doesn't matter because I won't go!" "This is just like Mikey!" "Instead of talking face to face, he sends a little weird guy to stare at me!" "Hehe omg!" "Sorry for calling you weirdd!" "I tend to bully small children when I get moody!" "My B!" I walk around the room for a bit. I interact with her again - "Mikey never paid any attention to me, you know??" "I wanted to teach him a big ol' lesson!" "So i'm playing hard to get by wandering into the woods and maybe dying?" "I think he'd care a lot if that happened!" I probably could've interacted again, but I accidentally left the room and was back in the normal area. Am I the first to find this? If you guys know anything about this secret, tell me

0:36 flowey was having NONE of that 😂😂😂

There’s also a lot of FUN value secrets in Undertale Yellow, I experienced one without even knowing because I was playing blind, lol.

UTY Integrity lore goes hard

little did shayy know, they did actually put a superboss in the game

If you go to the shop at the apartments in genocide, you can see something in the darkness

the best part is that macro froggit has the same layout color changing thing as ceroba and martlet

Hell yes, more stuff about Undertale Yellow

I love how the first secret is literally trolling flowey He literally goes all: "OH YOU LITTLE PIECE OF SHIT!"

Something I did on my run was use the matches on the piece of wood in the mines. I cannot believe they added a special animation and solution just for that.

slurpy also sends you mail after you free him from the pole with the warm coffee

I like how Slurpy is a whole fetch-quest to cool down the coffee to a more manageable level (and you can't just grab some ice or something), in part due to the inn having McDonald's temperature coffee.

I need to see a fight in between the mega frog and the cat god.

I knew there was more to the micro froggit stuff! I found all 3 normal rooms, but I didn’t find the Steamworks one. It’s too bad you literally can’t ever play the game again unless you reset.

Toriel: Actually rescues Clover. Flowey: TIME PARADOX!

Oh wow, I never expected so many uploads. This game REALLY blew up fast!😄

Also you can get the Band Merch Pin even in Genocide as long as you go ahead without killing every monster and get it from the monster lady, you'll have to play the Shufflers game tho. You can't get the Silver Scarf though, Coffee guy won't show up if you get to honeydew early or late in genocide. Then just go back and kill the last monsters.

Hi Shayy I loved watching your stream on this game!

6:30 silver scarf is broken in AXIS fight due to the fact that you can force extra turns to heal

The car driving frogs in Macro Froggits fight look incredibly similar to Mother 3's car driving save frog

13:20 Look at the *MEGA FROGGIT’S* face frames! 🐸 👁️👁️ 👄

They really like to hint towards the Blue soul.. don't know why

This is basically just a golden item showcase. The rest are like half secrets. Except for golden cactus. That one was incredibly obvious, where as I didn't even know I was supposed to look for the other golden items.

Undertale yellow have fluid animations more frequently In base Undertale its less frequent
