Important timestamps in the description if you want to look through the secrets! Enjoy. :)

Merg: If you name yourself gaster, the game just resets. People named gaster: *_*confused sweating_*

"You know rectangles?" "They're like messed-up squares?" *-Ralsei 2018*

"You know rectangles? They're like messed-up squares?" *Mettaton will remember that*

this video is 50% Ralsei Bullying...it hurts my feelings...

I love how when ralsei is annoyed it just shows a badly drawn sprite of him.

Ralsei: kris, you can stop hugging me now... Kris: *_I’LL STOP WHEN I WANT TO_*

I like how Gaster is still a huge mystery even till today

My theory for the tree/egg man is that it's just tem in a suit.

Kris using the Cell Phone in the Dark World: Kris: "Is this the krusty krab?" Phone: "No, this is Gaster."

She protec She attac But most importantly, She eat chalk for snac

I'm slowly but surely getting dragged back into the fandom

I really can’t explain how excited I am for Deltarune to be fully released. It’s going to be such a great game, I can tell.

"I've never hugged anyone before"-Ralsei *Internal crying intensifies*

it's rude to talk about someone who crashes your game

It must hurts Ralsei’s feeling so bad when destroying the Manuel ;-;

10:45 i am WHEEZING "well its not like i can dress up as a goddamn monster" i cannot breathe

* Gaster crashes the game because you typed in the name * Me: *OF COURSE* *OF COURSE.*

"Beware the man who crash your game"

The way it immediately cut from the overwriting save file to kris ripping his soul out jumpscared me a little ngl

Hugging Ralsei is so adorable...

I love how it just makes a cheering sound when you flush the toilet as if it's a huge accomplishment

Gaster in Undertale: *dark aura* Gaster in Deltarune: heya kid, here, take this egg

I love how Ralsei is first shown as a mysterious prince hidden under a dark cloak, but the fandom has turned him into a maniac with a gun lmao

I love How Ralsei blushes when you stay too much with him XD

Gaster's life has *really* hit rock bottom if he's giving eggs to random people.

The man behind the tree is actually just Danny DeVito, offering you an egg in these trying times

Yeah I can see the Gasterness in Shawn's face. He's just missing the other scar and his wide eye is on the other side.

Ralsei's reactions to getting hugged are the cutest thing ever

Me: *Finds the secret room.* The man behind the tree: May I offer you an egg in this trying time?

(You tossed the Manual hard.) (Its pages scatter in the wind.) Ralsei: Am I a joke to you?

Was watching some of your videos and came across this one, which I hadn't seen before, and I just wanted to say thank you SO MUCH for including that bit of Gerson dialogue at the end. When I first played Undertale, I exhausted as much dialogue as I possibly could, especially so with shopkeepers, and when I saw Deltarune first release, I made an IMMEDIATE connection to Gerson's dialogue about the emblem. I hadn't seen anyone else mention it though, only just "Deltarune" being an anagram of "Undertale". That was a detail I absolutely adored, so I'm glad it was included in this video!

in an undertale neutral route, right before omega flowey he says ‘monsters, humans, everybody’ the ‘everybody,’ face he makes is seam’s button eye.

“You did not put a bath bomb in the toilet again, did you?” AGAIN?

"You know rectangles? They're like messed-up squares?" he's not wrong, honestly

kris: moves box ralsei: uh i dont think thats right susie: *INCREDIBLE JOB!*

Decided to rewatch Deltarune and that face from Ralsei just gets me every time xD 9:23

"During our adventure, if you want to hit me.. that's okay, too!" Ralsei is so pure omg

More Secrets: Randomly throughout your playthrough of Deltarune, you can look at Kris's stats and see a dog that is asleep, and sometimes Ralsei's Kindness stat turns into Dogness If you try to drop the egg the game responds, "what egg?" and the egg disappears The room after the maze where you have to not follow Lancer and Susie, you can go out of bounds. If you try to call inside this room your game will crash. Kris is an anagram of Frisk but without the F The .exe file name changes as you're playing the game from "The Dark" "The Return" "The Death" and after you beat the game it turns back to "Deltarune" After you beat the game, you can start a new game and instead of going to school, you can go to sleep. Going to sleep makes you spawn in the Dark World. If you buy a Spookysword and keep it until the end of your playthrough, when you return to the town, the item in your hand will be a "Halloween Pencil" If you make your machine all duck, the confirmation changes from "This is your machine" to "This machine sucks ass." If you look at in the beds in the card castle, Kris's rank will change from Leader to Bed Inspector If you give Toriel the flowers from Asgore, and leave the house, the trashcan's floral scent increases There is unused dialogue in the game's code which seems to be Gaster You can go into your save file and change the room number and move to any room in the game. If the room number is higher than 130, your save file turns into a sleeping white dog and your .exe file changed to Dogtarune

Kris: *goes behind tree* Gaster: Egg.

A theory I have is the entire point of Deltarune is it's an experiment. The "vessel", the alternate timeline that feels so familiar and yet so wrong, there's something off about all of it, Kris ripping out their soul..... what if the Gaster tie-in is it's literally an experiment he's doing on a human

gaster be like: "it's dangerous to go alone, take this!" *hands egg*

"Are you sure you actually know the legend?" "Look." *No.*

when the shopkeeper says darker yet darker: "frick"

Theory: Gaster used to be a scientist/teacher at the school, (in the empty room) who found the portal to the dark world coincidentally in the school. He then set up a lab, and went into the dark world. He fought his way back to the real world, but he wasn’t the hero of the prophecy, so it instead sent him to the world of Undertale. He wasn’t the hero, so he couldn’t return back. He set up a lab, meeting people he knew from the world of Deltarune in the underground. He enlisted Alphys’ and Sans’ help, and got to work extracting and infusing determination into monsters. He eventually made a mistake, resulting in an accident bringing him to the dark world again. He found Jevil, and made friends with him, regaling stories of the underground, and teaching him about choices, and the futility of them. All the while, Gaster was trying to find a way back. He never did. One day he found a strange glowing orb. It was calling to him. He reached out to it, and felt power. He then lived out the rest of his life, and on the day of his death realized he still had so much to learn. He tried to keep his eyes open, as he was determined to live. Eventually they closed, and he saw a blinding light. He was back at that exact moment where he touched the orb. I think the save file that Kris overrides is Gasters, and that being in the accident with the Determination Extractor infused him with determination. He then went on the Flowey path, trying and testing everything he could to leave the dark world. It eventually drove him mad, so he ran and hid, waiting for the hero to release him back to the real world. I don’t know why he gave Kris the egg, but I know it will end up playing a part somehow. Gaster will return in Deltarune Part 2. This world is his experiment. And I think we will find this next experiment Very Very Interesting

I love that ralsies face while speaking looks low quality when he's annoyed

Ralsei is NOT paid enough to deal with some of this stuff. He's an innocent little bean and is too sweet.

I'm sorry, I just find it so sad when Ralsei says he knows nothing about hugging. Like, I just wanna hug him more!

9:42 Ralsei still does that in chapter 2

“Kris, don’t listen to him, you can be a box” My friends when I’m playing hide and seek

*Throws fluffy boy's manual.* Me: You have done a crime far worse than a genocide route

14:17 you can access this room consistently by starting in the right room, going left and holding right while the screen goes black to transition between the rooms. From what I can tell it's easier in full-screen mode.

"Lets remove this world and move on to the next" the seller's friend said Now pause on 13:47 Its all linked to chara

"You use items, and, um, something happens" > You used the Glowshard. *_But nothing happened..._*

*It's rude to talk about someone who's listening..." "It's rude to talk to someone who's not listening..." edit: guys this comment isnt funny stop liking it

I'm convinced that Gaster is gonna be the main antagonist of Deltarune

"I was a box for Halloween once." *CHILDREN SCREAMING*

"The only thing in the fridge is a jar with a single pickle'" "You put the egg in the fridge" "There are 2 eggs in the fridge" ????

It's rude to talk about someone who's listening...

If you go back to the beginning when you get out of bed you can actually go back to sleep and end up somewhere that you’ve seen before

Huh. Jevil and the Egg both share something, it seems. They both makes no sense/unimportant but also makes sense/important

Waaait a minute I just forgot! In undertale, the picture of the three people were like kris, ralsei and Susie, their both a trio, the next thing is that it says in the picture "don't forget" which is the song for the ending of deltarune, I like where this is going

that microsoft paint ralsei sprite is legendary.

1. I stood on the manhole, and went to the bathroom, and when I came back I saw onionsan! 2. DYK that Clam Girl's update came out a few weeks before Deltarune was released 3. Like Gaster's room in Undertale, the room with the man behind the tree is the only room in the game that has no wall boundaries. 4. The sound near the bunker is Gaster's theme slowed down by 666% 5. Seam's button eye is similar to the face that Omega Flowey makes when he says "EVERYONE"

15:47 i found this by accident and that scared the hell out of me. I was so surprised.

friggin ralsei has the most patience I've ever seen any character have

The egg proves that the darkworld is real because you can take the egg of the darkworld to the city.

4:59 thats what we called: Ralsei abuse

I love how I found a lot of these secrets on my first play through, it made me feel a lot more special

10:52 wow, for once Susie is the once saying "FOLLOW YOUR DREAMS KRIS!! IF YOU WANT TO BE A BOX, YOU'RE A BOX"

Man give egg egg will hatch Kris proud parenttt

Entry number seventeen. Remember in the True Lab when it gave you a bunch of backstory on what Alphys was doing to people on those signs? It labeled them through the numbers, each entry. There was a missing number. 17.

I enjoyed watching this a lot, laughed my ass off at the beginning and when it got serious it was pretty interesting. Awesome video :D

"Lancer and Susie's blueprint looks like the one in Sans's secret room." Gaster, working on the blueprint: Ah, yes. My greatest creation. The D.U.C.C.

I think we, as the players, inserted ourselves in Kris, our vessel to interact in the world. But Kris already had a life, personality and story (as shown when you overwrite Kris' save file), so at the end of the game, he breaks free from our control to be his normal self again... And apparently, "his normal self" is not someone benevolent...

I know that spent a lot of time, but I'm going to say it the same, at the beginning when kris and susie go to look for the chalk, susie when giving the option to choose the decision says, your decisions do not matter, it is not much but they would agree with the end because be it massacre or pacifist the route the end is the same.

1:38 I thought you were going to put "sus" lol

Maybe it's just me, but doesn't all the "happy town" setting give somewhat the feeling that something is wrong, or maybe just kinda off? This is the outside world, monsters are (supposed to be) free, as if this was the best outcome possible of a Pacifist Run in Undertale. Or maybe some AU setting where war between humans and monsters never broke, so the two races always lived peacefully together. Still... 1. There are no humans in town, except for obviously Kris. Humans aren't even mentioned, monsters don't talk about them, almost as if they didn't acknowledge their existence. At first it struck me how Kris was the only human kid in the class, but then I realized that he's the only human kid in the whole place. 2. No one has the happy life they seemed to be going to get at the end of Undertale. Undyne and Alphys are complete strangers when they're supposed to be a couple, Bratty and Catty talk about one another as horrible people when they should be best friends, and even the two soldiers (which should be lovers) are still in the "bro" phase. Alphys is clearly insecure and lonely, and when you knock at Napstablook's door it seems like Mettaton is responding (with that trademark "darling"), but he doesn't want to open the door out of shyness, which is very strange of him. Not to mention what's happening to poor Asgore. 3. What's the deal with Asriel. Yeah I know this is sort of The Big Mystery of the whole game, still I can't help but get an uneasy feeling every time someone mentions him or he's referenced, almost like something bad happened to him but everybody is pretending "he just went to college". Has anyone noticed how the "two halves" of the room look different in Kris' room? His side is almost dull, while Asriel's is all shiny and covered in trophys. Everybody remembers Azzy fondly and talks about how him and Kris were close as brothers, and probably Kris misses him greatly. Ralsei (same letters as Asriel, also "the prince of an empty kingdom") looks almost the same as Az, and that's probably why Susie was so shocked when he showed his true appearance. Is Kris somehow projecting nostalgia for his brother into that "other world"? EDIT: this might be me speculating too much, but Toriel mentioned giving Kris a headband with red horns because he wanted to grow horns when he was younger. And we all saw Ralsei having pinkish-red horns instead of white ones, right? 4. The town itself gives some creepy vibes, like the long, silent road which leads to the ominous red door. Music is a very important part of the Undertale universe, and the most powerful track is indeed silence. When silence happens it's disturbing, almost chilling. That long road was long, like insanely long, because of the silence. And then there's the red door, locked, with the Gaster theme and green vines covering it. I'm probably not the only one who tried to make a phone call there, out of the feeling that the phone wouldn't have worked. It did, and it was nice to hear Toriel's voice, it made me almost snap out of that feeling of extreme danger I was having. Also, a part of the road is blocked by police barriers, and that seems to be the only way out of town - the other side is closed by a lake (with no bridges and no boats), and everywhere else it's forest. If you wander around for a bit, it actually feels more trapping than the Underground somehow. 5. Sans. he acts like he knows Kris, or better, likes he knows you, the player. He's all goofy and jokey sure, but he does say some pretty interesting stuff "sans style" (and I don't mean the "befriended" your mother thing). I'm sure everyone pretty much screamed upon seeing him (I sure did) and rushed to speak to him. And his answers can be summed up with "why are you acting as if we knew each other? because we don't know each other. Except we do, but I'm not straight up saying that". He says so in his usual almost taunting fashion, giving remarks like "you can't just jump into friendship, it takes time", then proceeds to give you his phone number, but it's not his real number. Just a prank, maybe? He is indeed a prankster. But aside for the farting handshake, sans' jokes have never been just simple jokes. Even the secret codeword thing was disguised as a joke. And yeah I know I said that I didn't mean the "befriended" your mother thing, but actually, sans just said he has no idea who Kris is, and then openly states that he knows both his mother and teacher. And again, he taunts you brutally with the "I befriended your mother last night" thing. Enough for a Megalovania background moment! To me, it felt like sans was telling us "I know who you are, and be damn sure that I'm watching you". TL;DR - The whole monster town felt somehow like a strange dream, where things seem to be nice and fine but there's an uneasy feeling creeping around every corner, keeping the player on edge. I am super hyped for Chapter 2, and thank you Merg for this video covering some of the most juicy secrets (like the Gaster theme and the egg thing!).

beware of the man who speaks in eggs

I saw him type "sus" and i freaked out-

*"Beware the man that if you type his name on the fallen human will restart your game"*

13:00 Tbh, the blueprints in Sans' secret room looks like actual blueprints while Lancer's blueprint just looks like a mess.

"Y'know, rectangles? They're like messed up squares"

3:16 ralsei in cape look like riverman from undertale

I kind of thought about it, Deltarune is just one big survey. You are asked about your prefences. The first chapter of the test seems to be overall pretty basic, some optional questions are avaliable for fun. The second chapter is a little longer and has a lot more to answer, optional questions are more complicated compared to CH1's optional questions. *No matter how good or bad, you will always pass, it's a survey after all.*

I basically just watched 10 minutes of screwing with Ralsei.

"*You know rectangles? *They're like messed-up squares?"

"the narration during your character creation" that was the move that made Shakespeare cry

"After that, no matter what you will get a Manual which doesn't actually help you, so you might wanna throw it away-" *"NO."*

The Ralsei blushing thing is effin cute, I had no idea about it! My heart...!

"If, during the adventure, you want to hit me, that's OK, too!" Can't tell if Ralsei is just pandering to the hero or if he's secretly super kinky

I like how the egg thing is a meme and lore based at the same gime

18:37 This line from Seam connects to the whole thing about your actions really not mattering, because despite what you choose in Chapter 1, the game always makes its way through.

Some other cool secrets in the game: - You can equip (or try to equip) armor/weapons, or give food to your party members, and they'll say unique lines. - When you first get Ralsei, if you walk instead of run, he'll comment upon it. - Depending on the party member, if you give them a Choco Diamond/Hearts Donut, they'll recover 80hp, 10hp more than the Darkburger. Save the Choco Diamonds for Kris, and the Hearts Donut for Susie. - When you get the White Ribbon, if you equip it on Ralsei instead of Kris, he'll act surprised and ask him if he looks cute :) - Now, this one is pretty interesting. If you die, mashing [Z] will make your party instantly go back to your last save point, instead of having to wait through the game over cutscene. - When you wake up at the beginning of the game, if you go back to sleep, you'll skip school, and go straight into the Dark World. However, when you wake up there, you can get a Wrist Protector, which can allow you to skip lots of text by holding [C]. - Not many people know about this, but when you follow Susie/Susie follows you, if you run instead of walk, in the Overworld and in the Dark World, she'll comment on it. (Thanks WolfLink!) That's all I know, but if I forgot something, comment below!

Something I personally found interesting when you try to sell devilsknife (idk about jevilstail) to seam he says "that's nothing" the same text that you will get if you try to sell an empty slot

Gaster the one lost to time and space that only few knew. Gives you an egg cause why not

The phone call sound is also a very slowed down version of Muffet's laugh.

What if... GASTER WAS AN EGG?! AND HIS CRACKS ARE JUST FROM PEOPLE DROPPING HIM A LOT?! That explains EVERYTHING!!

Someone said this before: Jevis said that we made a prison for ourself and throw Jevil to his little freedom (or something like that). Could this mean that it's a reference that Jevil have "freedom" of choices and others not? Jevil knows that he is in a game, and the monsters are just participants that only follows the plot and can't make a choices other than what's written in the plot. He also said "I can do anything", which means he has a freedom of choices. He can do anything he wants, not bounded by the plot. I don't know, but it's pretty interesting...

I think Toby and us are on the same page. The low quality sprites are hilarious. Especially Ralsei’s.
