I've gotten quite a few comments regarding the money thing for the Tem Shop, mentioning the Dog Residue instead and even saying it's better. I'm more than aware of that method! However, the method in this video is way, WAY faster. Dog Residue items are 1G and max out at only 4G after bargaining -- Cloudy Glasses are 50G and max out at 65G after bargaining. Each trip nets you over 500G. It's not even remotely close in terms of efficiency, I'm just saving you all an hour of your life!

imagine being such a psychotic mastermind at making indie games that almost 9 years after your game released, people are still finding new secrets

Undertale is STILL a 2015 2D role-playing video game created by American indie developer Toby Fox.

7:50 I guess Mettaton just promptly ripped off his own limbs for a more dramatic exit

There are so many facts in this video where I was like “Pfft, I know that” and then you kept going on and then I’m like “Wait, WHAT”

That thumbnail gave me "I remember you're genocides" vibes

6:40 Theory time! The bandage lets you flee easily is because the monsters are like "oh they're hurt and trying to run away... Ill let then run" I think its like that

now we all know that gaster got stuck in the void by accidentaly going out of bounds at grillby's bar

If you don’t flirt with Papyrus, some of the text in the date sequence is changed to be more of like a hangout.

10:40 Ooh that's actually how my chat beat it in Twitch Plays Undertale. They also accidentally found the missing wall bug, since they all held right, trying to reach the door, unaware there was a lack of hitboxes over there.

3:06 “it’s time for my special attack-“ *dies*

10:20 isn't there also a small chance that it will say something like "CONGLATURATIONS" instead of "CONGRATULATIONS" when beating the puzzle? I feel like I remember something like this Always cool how there's so much details in this game Edit: it seems I have been misinformed, that was never a thing

Shayy traveling to his secret basement library to drop 10 UT facts every few months (ancient knowledge thought lost for millenia)

It's super cool that you were able to make me say "Oh, I know this," before adding on more details that I wasn't aware of. You put a lot of effort into making this video :)

6:14 For anyone curious why slot 1 is slot 0 in the code, it's because computers count 0, 1, 2, etc. This isnt undertale specific either, this is in almost if not all computer/operating systems

There's over a thousands comments here, so in the low chance you see this, I wanted to share a discovery I made 7 years ago which I've never saw anyone else mention before. You can, in fact, write 'z' or 'x' during Mettaton EX's fight in the PC version of Undertale. The secret lies in the Caps Lock key. Pressing the Caps Lock key will input the last key press on the keyboard, so if you input z, followed by Caps Lock, you input z. This means that special keywords such as "foxy" and "sexy" are possible.

Fun fact for people who don’t know yet: using cloudy glasses and torn notebook (+inv frame armors and weapons) actually semi-counters karma/damage taken in the sans fight, and there’s a great way to showcase this: normally, doing nothing with regular armor kills you on the first attack, but with cloudy glasses and torn notebook, you can survive the first attack by doing absolutely nothing

Here's one for Deltarune that I found on KZfaq recently: Holding the A key while in Kris' ACT menu or a party member's MAGIC menu in Chapter 2 will show what S-Action/R-Action/N-Action can be taken against each enemy. Really not too useful because a majority of them are just called "Standard" but it does exist for some reason. Possibly a leftover debug command? Not too sure how common this knowledge is, but it sure is nearly useless trivia.

4:59 the fact that there is no actual sprite for the cowboy hat in UT, so Clover’s hat is used instead

its truly fascinating how a game made mostly by a guy in his 20s in 2015 who just used to make mods for earthbound, can have secrets alot of people still dont know in 2024... 9 YEARS LATER...

Fun fact: shayy will be in the undertale movie releaseing this year (toby fox told me this, i mow his lawn)

i have a secret you havent covered: if you look in the files of the game you can find a set of sprites for a character named "frisk" whoever they might be. If you boot up the game and start a save, you actually will spawn in as the character

10:39 This was found by HalfBreadChaos's "Twitch Plays Undertale" stream, too!

5:39 solve the piano puzzle. Get dog residue. Use dog residue. Sell all dog residue except 1 to temmie. Infinite money

11:05 is actually an example of recommended game design. If your player is struggling with a puzzle and hints are not cutting it then you should solve it for them to ensure they can continue to have fun

8:33 This is probably a reference to that one door in EarthBound that you have to stand still in front of for 3 minutes in order to open it. Makes sense, since (as everyone knows) Undertale was inspired by EarthBound.

Its kinda crazy how some of these secrets wouldve never been found if undertale wasnt popular

So Gaster fell into his own creation, the cracked floor leaf puzzle

Fun Fact: The Slow Soul might take inspiration from the Touhou series, where holding the shift key would slow your player character down to be able to dodge more precise bullet patterns. In the Switch Version of Undertale, you can clip in between Lesser Dog and the table he's sitting at in a very precise spot. This might work in other versions, but I do not know.

10:30 You have no idea how stupid I feel after struggling with this singular puzzle in SOOOO many runs

here's an idea: Did you know that different names give you different flavour texts upon entering? [Give Examples]. Well you probably knew that, but did you know that you can make yourself have no name? If you make your name a single character, and then press the x / shift key (to delete a character from your name) on the same frame you press the done button, your name is nothing and you've clicked done at the same time. This usually can't be done, but Toby Fox found out about this, and the game says "You must choose a name.". edit: might be too simple but whatever i guess. it's an idea. also did you know that the dog searcher thing in the papyrus date (at the top right) can be a diamond instead of a square? you actually got this in your 1.02+ AME WR. (it's a glitch)

6:05 as a gms2 programmer, this hurts. Why didn't he just use a "switch" statement 😭

11:00 LMAOOOOOOOOOO MY SISTER PLAYED THE GAME AND SHE DID THIS COMPLETELY UNINTENTIONALLY

7:05 there is small issue that you have to not equip specific armor never before the battle starts because game checks if you have worn any other armor than bandage and gives around 50 points or don't give them at all for that armor piece (i forgor if it actually gives you points)

2:20 for those wondering: this did in fact work on the switch version at launch when holding down all the directional buttons on a joycon but this has since been patched out

"getting lost in the endless void. reminds you of somebody, doesnt it..?" SHAYY HAS SUCCUMBED TO THE FANON

Whoa, I didn't know any of this! That's because I haven't finished the video yet!!

Shay you are my favorite KZfaqr ever. Thank you for making these fun and entertaining videos!

7:41 lol the first time i beat mettaton, i didnt even get up to the part where he loses his legs, so i was so confused the next time i fought him and he lost his legs. but doesn’t he have this explosion effect when the fight ends? that might be the implication he lost his arms and legs there edit: ok it isnt an explosion sound but maybe

I’m blown away by the fact that people didn’t know about the leaf puzzle because I was apparently so bad that I got the floor to not break on my first playthrough

Having watched a ton of secret videos and icebergs etc its so rare I find anything I dont already know but your last video was amazing and actually told me something new so really excited for this one Shayy ❤

9:36 I discovered this one by myself! ❤

I once tried to play a no save file playthrough, but i lost it when I was at grillby’s. Basically, I went to go talk to the dog playing poker against himself, and accidentally walked through him or around the table somehow, causing me to be stuck behind the counter forever (Grillby doesn’t have a side talk sprite btw). I’ve never gone near that dog since in fear of that happening again. I did this on switch btw.

Always really love watching obscure fact videos where i actually DO get to learn a new thing or two! Really enjoying the new video styles you've been trying recently and would definitely love a part 3 👀

Never been more proud of myself for actually knowing a few of these.

I hope Toby makes an update so that the glitches aren’t fixed but instead adds secret events and dialogue like how doing them enables a Hard Mode like Spamton Neo or sans making fun of you for the Sea Tea Glitch Same with the Punch Card Glitch like how Fan-Games like Deltatraveler and TS!Underswap hide secrets that can only be accessed by using the Punch Card Glitch And also teaches the player about slowing down, perhaps from a Canine Dog 9:27 *FRISK DANCE*

i don't know why but the idea of speedrunning mettaton's fight by changing your fit over and over is the funniest thing to me

Love when Shayy comes out of their cave to drop a new video, and then proceed to never be seen again! I wonder if a part 3 is possible though...

5:00 no image avalible

8:32 I found this out by doing exactly what the sign said.

Honestly, there are so many details in this game that it's honestly sad that a majority of the fandom just boils down the themes and characters into something extremely basic. (Example: The fact that there are leaves place in the pits in the ruins and flowers placed in the dump is because two of the souls likely fell to their deaths in those areas.)

I actually knew about running on the castle screen in Waterfall, thanks to the amusement I got from flopping against the upper walls of any room I was walking through. I was actually a little disappointed that Toby Fox fixed that for Deltarune. Wait, you've NEVER seen anybody talking about the leaf room puzzle? I thought that was well-known by now!

0:46 just wanted to point out that the game does mention this feature when talking to a froggit in the ruins in the room after napstablook's room. It said that if you ever wanted to go slow just press x but i didn't realise what it meant by it until now. Cool vid

you know that it’s way easier to get the Temy armor if you get the dog residue from the artifact room in waterfall then just use it after emptying your inventory sell all of it except for one then use it and rinse and repeat 5:24

woah i remember following your speedruns back when i was learning how to run this game!! glad to see you still in the scene & putting out good content!! keep it up (:

I actually want to further elaborate on the out of bounds area for leaf puzzle room: Once you appear offscreen when going right, you can hold the right arrow key and up arrow key to continue going in that direction, because after approximately 5 minutes of holding the right and up arrow (both at the same time), the screen will shift upwards slightly, indicating that you are now past the hitbox barrier. When the screen shifts upwards after doing so, you can hold left to backtrack back, so around another 5 minutes later, your character will appear back on-screen, and you can explore. P.S. Some areas of that particular room when out of bounds, some areas like the bottom right of the screen, it crashes the game oddly enough.

4:22 as far as i know, the grind times are supposed to be incredible painfully long, as the game trying to stop you. This ending is meant to be hard and tedious to get, and make you feel bat about everything. I'm guessing the high step count is meant to be there, to add to the unpleasentness

5:16 fun fact (that I think that works) for neutrals the death counter applies to you also killing monsters so I did an aborted genocide route at papyrus doing over 25 kills and when I got to Temmie, the armor was 750 without any deaths on my end

Seeing the Undertale community still active and constantly finding new things is one of the most wonderful feelings in life. Almost if... It filled us with determination.

Jeepers! These facts made me audibly gasp! Thanks a lot Shayiti for showing us these goofy secrets!

Fun fact 11: in torn Apron room (Napstablook friend request room) if you go to the far right corner you can actually see some random ass man just standing there… Menacingly

5:08 I bought this armor for the original price... (It took me about 1 hour to get the money) :P

I literally only didn't know 4 of these (6 if I were to count both out-of-bound glitches at grillby's bar and the puzzle sequence)... Thanks Shayy for making me feel like a total know-it-all

I mean, even though I am still shocked about there being a third way to reach Mettaton EX, it's surprising that I know about like 95% of this game's little details or secrets. Exploring each new chapter of Deltarune reminds me of all that time I spend learning about Undertale

11:34 LUMI OUTCORE?!?!?!!?!?!?!

5:56 - THOSE DAMNED IF/ELSE STATEMENTS AAAAAAAAAGH

I LOVE THIS SERIES

I haven’t seen anyone mention this and I just found out recently. In waterfall, there’s a Shyren in the room under the piano room. You can hum a bunch of times to start a concert and spare them in a cool way. Later on, when you sing to Knight Knight, it says you sing Shyrens song. Cool detail!

0:22 "the majority of my viewers arent subscribed" Shows 50% of viewers are subscribed:

I honestly know about Slow-Soul because of Undertale Yellow.

The press X to slow down mechanics is from Touhou made by ZUN, the game Toby really like when he is 11. Heck, if Toby didn't touch Touhou at all that day, the Undertale dodge bullet system will don't even exist, as well as a great chunk of Undertale OST, the whole game systems and music will become Earthbound like.

10:55 oh yeah that i tried in deltatraveler

HOW WAS HIS NAME GASTER? 3:00 (normally it would reset the game upon naming the human Gaster)

Fun fact when you buy alot of cloudy glasses you can store them in the box because there is another box at tem village you can also use ur phone in Pacifist and neutral after going into the lab

please more. i love these videos, i love seeing anything new in the game im playing for years now

Lesgoo more secrets 👀

Under an hour gang assemble

A cool fact is supposedly the reason Undertale's file system is so strange is because each file correlates with a separate entity capable of using saving and loading in the games lore, being of each of the 7 souls as well as your save and flowey's.

It’s really funny to realize that soul slow movement is a feature few people know about due to never being explained by the game, when I know in my experience I found it during the tutorial by complete accident while trying out the game on PS5. Nice thing about having less buttons to play with lol. I thought it must’ve been a new addition or something like that

YOOOO SHAYY UPLOAD

8:47 I love the username and the (mis) pronunciation. I think it's Yam Alpaca. (Yamal, hehe). Where do people come up with these names?

Don’t remember if you’ve mentioned this but one small obscure detail is that the sprites of Royal Guard 1 and Royal Guard 2 are labeled “bara”. Bara is a word for gay manga… Usually featuring muscular men (like RG02 when he loses his armor). Bara, BL, MLM, “Yes, [Topchef] is a top (pause) Bad. Bad”.. Toby just casually dropping gay slang like a champ. 🫡 I salute you, sir. (No. It’s absolutely *NOT* speculation on IRL sexuality. That’s super parasocial and creepy. This is just an observation.)

wow, usually with these types of videos i know all the things mentioned, but once again i didnt know some of these! good job mr. shayy undertale/deltarune/deltatraveler/undertale yellow/TS underswap

11:16 it happened to me on my first play through

2:37 No one gonna mention them being named gaster

Ty for the video! Good to see your passion to this game 😊

Finally! In almost all of these types of videos, I already know these stated facts, but this is an exception! Actual new information for me!

6:35 I knew this, you talk about it a lot.

5:29 you can get dog salad and make infinite dog residue! And sell it to tem

I'm amazed that after nearly a decade I'm still finding out new things about this game, I'd love to see a part 3!

GUYS WE KNOW HOW GASTER ACTUALLY GOT LOST IN THE VOID! He just tried to do a funny out of bounds glitch 😔

Cool!

Blud think he sambucha 11:11

Almost thought i knew the last one. ..and then i got baited. Shayy is truly one of the few undertale experts, and def knows more than me tryna know every possible secret. Def cool man, i'm deciding to subscribe since i already like most videos by default, you deserve it 😁

the cloudy glasses and torn notebook are actually very useful for the sans boss fight, too! if you use them, you won't get an i-frame boost, but you will somehow take less damage from karma! if you're struggling with genocide, i recommend using the cloudy glasses and torn notebook, they really helped me out with my undertale Nintendo switch playthroughs, especially since i can't really do many of the glitches used to make the sans fight easier.

3:30 that name is smth off about HOW IS IT GASTER

4:04 wide frisk wide frisk

Hey shayy! I got a video idea i would find intrusting, i’d really like to see you showcase every glitches you know! Anyways, great video!

Shayy I would like to thank you for this vid as you have helped my bf fight mettaton and he's really happy cause he can now finish his first ever run he's played it before and got stuck at mad dummy and has gotten past it this time thanks much love ❤

4:45 I didin't know she was Female
