150 dollars for not playing Undertale? I know, right? These cops! I would've fined you 500

dollars. You haven't played Undertale yet? Really, you too? Play Undertale. Fine, fine!

Okay, I'll play Undertale. Here I go. I'm going. I'm playing Undertale. It's Halloween!

Just in time for my Top 10 Secrets of Undertale list. The video you're about to view contains

a number of spoilers for the game, Undertale. Please only watch if you have already beaten

the game or have no intention of playing it through yourself. You've been warned. In our

number 10 spot. Isn't that cute? I got a lot of friends out of that! I beat the game, they're

all my buddies. I got a sweet new goat mom and goat dad. It-it couldn't get better. *goat

bleat* Now let's kill everyone! Well that was fun, now everybody's dead. What the hell?

You said we were gonna go walking in the snow. We can't go walking in the snow now! Don't

worry, I got it figured out. I just wanted to see what would happen. I have a solution.

A solution to-to the corpse in our living room? Yeah, man, a reset button! A reset button?

Yeah, watch! You're an idiot. I believe I fixed the reset button... and there she goes.

One last pass at us... one last glimpse for out pacifist ending. Nope! There, all tucked

into our bed... please don't wake up. Pro tip, if you're gonna do a pacifist run, don't

do a genocide run first. It messes things up. In our number 9 spot. I'm coming to save

you, Alphys! Don't-don't do anything irrational in the bathroom, I'll save you! Just gotta-you

just gotta sit-sit tight! I'll-I'll be right there! This isn't a bathroom is it? So you

managed to beat Omega Flowey, did you? Well, congratulations! You got the neutral ending,

but if you wanna get the true pacifist ending, you're gonna have to take a trip to "the true

laboratory." Next you're gonna tell me that Alphys keeps her pet lab inside of the lab

inside of her lab. Oh, she does have a pet lab, does she? Inside of her lab insider of

her lab? It's a lab made out of five labs, therefore it's like 15 labs worth of labs!

I need an aspirin. While their are a lot of weird things in the true laboratory, probably

the strangest is in this room right here. The giant mechanical structure you see before

you is actually the bare bones skeleton of Flowey's neutral boss form that you fight

prior to entering the true laboratory. Just in case you didn't get enough of that Eldritch

Abomination that you just finished fighting. Isn't he beautiful? In our number eight spot.

In our number seven spot. Okay, so I just have to go this way and eventually I'll make

it to the town and find a market where I can sell my gear an-- Oh, h-hey there little guy!

What are you doing out here in this frozen wasteland? Oh, you even got a giant sword.

Who has a giant sword? Yes, you do! Yes, you do! Aw... Hmm, mister puppy you drive a hard

bargain. Looks like i'm gonna have to give you pets, that's the only choice you're giving

me here. Who likes his pets, yes he does! yes he does! Y-yes... he does? Uh... I think

this is becoming a problem, dog. This is-this is now an issue. You know, with most dogs

they say that their bark is worse than their bite, but in your case your neck is worse

than everything. Have you considered seeing a chiropractor? Do dogs even have chiropractors?

These are all questions that I've never had to ask before, but thanks to you, it's now

at the forefront of my agenda, so good on you, dog. Good on you. In other dog related

news, Sans piles hot dogs on top of your head if you buy too many when your inventory's

full. If you felt your game didn't have enough hot dogs or hot dog physics... here you go.

In our number six spot. So you played through, you beat Undertale, you saw the credits, you

got whatever ending you wanted, and then you decided... "Hey, you know what'd be pretty

cool? I'd like to be one of the characters I met while playing this game. Sans. Okay.

Let's try... Asgore. This isn't working. Well gee, in Zelda I name my character Link, and

he's actually called Link, so I may as well call Frisk... Frisk. Ho-ho-ho, buddy, it's

hard mode! Let's do this thing! Yes, that's right. If you type in the name Frisk as your

name at the start of the game, you can actually play a demo of the hard mode that Toby Fox

eventually wants to implement in the game. This version features some off the more difficult

enemies appearing earlier as well as the introduction of some new enemies that were not previously

seen. Alternatively, you have the option of naming yourself Papyru, which is almost Papyrus

and, believe it or not, Papyrus will allow it. *sigh* You just want me to use this name

because you misspelled your own name in a word jumble, didn't you, Papyrus? I'm on to

your tricks. In our number five spot. So it's snow mystery that throughout Undertale, you

mostly play as a heart. So, what if I told you that you're actually the most boring heart

in the whole game? You're a red heart. Who wants to be the red heart when you have the

option to be literally any other color? When you make it to the end of the game, you find

a room full of coffins, and each coffin has a different color heart on it representing

one of the other fallen humans. One of the seven required to open the gate and free the

monsters from the underground. Now, there is a golf mini-game that you can play that

will sort of give you insight based on what weapons and items you're carrying and how

quickly you're able to get the ball into the hole, but the easiest way of telling how these

humans actually were while they were still alive is by observing the various bosses that

you encounter in the game. The simplest chart that I could possibly design for you is: Doggo

is the light blue soul because you have to wait to be able to attack him, Asgore is orange

because he prevents you from being able to use Mercy. He's the only fight that requires

you to attack him. Papyrus is dark blue because his ability causes gravity, forcing you to

have to actually acrobatically dodge his moves. Purple is most represented in Muffet, where

you're required to not only look at note cards to know what attacks are coming next, but

also the creatures that come to attack you form along note lines, like the notes in a

song. Undyne was most represented in the green soul because you needed to actually help her

in order to beat the boss fight, Mettaton was represented by the yellow soul because

you needed to shoot with absolute precision to be able to take him out during any of his

forms, and all that forms the colors of the rainbow. I hope this was an educational experience

for you. In the number four spot. We did it, Moomin! We made it through the entire game!

All of our friends are saved, it's a pacifist ending, we just have to go through that door

and end the game, and-- Oh, my gosh, Moomin, I can't believe-- Moomin, no-no,no-no, the

ending is that way. Okay, Moomin, I hope you're content. Welcome to Hotlands. It's still Hotlands!

Yeah, like, I guess the dialogue's a little bit different on some of the characters, I

guess that's kind of cool, but we really should go back to the ending. Okay, yeah, Waterfall's

pretty cool, Moomin, but-but-but we have to go back! You're losing focus here! The ending's

that-a-way. I can't believe you dragged me to Snowdin, Moomin. Moomin, don't be thinking

what I think you're thinking! If we go any further back there won't be any fast travel,

and then what'll happen to us? We'll have to physically walk places. It'll take like

an hour for us to get back to our starting position of the end of the game. I-I-I mean,

what. A-a-are you proud of yourself? Proud of yourself the fact that you made it from

the start of the game to the end of the game and then the end of the game to the start

of the game? Is that the point that you're trying to get across? That you can play it

backwards? C-cause Moomin, I tell you, I-I play a mean game of Frontgammon if that's

what you're after. Boy that was a really exciting thing we saw at the start of the game, wasnt

it, Moomin? I-I really hope that other people see it and actually go to the start of the

game after they beat a pacifist run before-before ending the game, Moomin. And-and they should

make sure to go through all the dialogue options so that they can get the full experience.

Th-that I think is probably the best way to go about it. In the number three spot. Now

Iknow the game just started Snake, but you should probably wait for Toriel to get back.

Huh... waiting... Right... I'll patch Toriel into your comms so it's easier to communicate.

I'm here, Toriel. Tell me what you want me to do... *barking* Stop, please! Come back

here with my CELLPHONE! Huh... In addition to that little exchange if you wait long enough

in the room she tells you to wait, you also have the option to communicate with her. If

you opt to not only call her mother, but then flirt with her twice after doing so, she will

react appropriately for your perverted behavior. Doing this also does have consequences for

the ending of the game. Be careful what you say, your reputation in the underground hangs

in the balance. In the number two spot. Do I write Papyrus in yellow or in pink? I don't

know what to choose! If you go to the room full of Froggits at the start of the game

and go to the third Froggit, he will offer you the option to remove yellow text from

the game. If you speak to him again afterward, you can also make the unhighlighted spare

options into pink highlighted spare options. Better yet, when you go to the garbage dump

later in the game and check one of the garbage piles, you can find those yellow words thrown

in the garbage. That goes to show you that even changing the color of your fonts has

consequences in Undertale. But Timbertaft, you say, I don't prescribe to either liking

the color yellow, or the color pink, or not colors at all, what can I do? Well, in your

case, if you happen to be into voyeurism, you can check a crack in the wall in the same

room as the other three Froggits to find another Froggit! Yes, that's right, aren't you happy

he's here? I know I am even though he doesn't actually do anything. You're welcome. In our

number one spot. Name please? Hoi's, I'm Temmy! You're on the list. Right this way, ma'am.

Too many things, lately. *sighs* NIce kid. Hello, good sir. Hello. I would like to enter

this establishment. Name please? I'm Timbertaft. You ain't on the list. I must be on the list,

I'm Timbertaft. Look, buddy. You ain't on the list. All right? Now, you-you don't wanna

go in there anyways, right? You get in there? You're gonna have a bad time. All right? Enjoy

this weather! See... the leaves are turnin'. It's Fall! Red. My favorite color. Well anyways.

Go enjoy the day. Do yourself a favor. You don't wanna get in here. That gives me an

idea. What now? Hey, w-why did you say that so close to me? He called me an idiot, he

did. He said, Oh, that's not gonna work. There's no reset buttons in life. Yeah, I'll show

him. Ha-ha! Hello, good sir. I am Timbertaft. Dude, I already said you weren't on the list.

All right? Perhaps you haven't noticed the red of my attire? What? As you can see, I'm

very... much... red. That doesn't mean you're on the li-- This is... perhaps.. your favorite

color, as-as-as some would say. You think just because you're wearing my favorite color,

I'm gonna let you in even though you're not on the list? We're all friends. You're an

idiot. Sans is an interesting character. If you confront him in the hallway and you ran

a neutral or pacifist ending, you won't have to fight him and he'll let you pass. An interesting

thing that you can do to him, though, is close your game at this exact moment and reload

the save prior to speaking with him. I think you might have gone a little overkill. When

you finally make it back to Sans, he's going to talk to you a little bit about what he

talked before, but then he's gonna catch on a little bit. He's gonna notice the fact that

it seems like it looks like you've already been through this. So as to ease the boredom

that was on your so ever expressive face, Sans decides that he's going to have you go

back again. This time, though, he's gonna give you a secret code. If you tell him the

secret code on your next arrival, he's gonna give you the keys to his bedroom. We're rich,

Moomin! Do you know how much we can rent out real estate in Snowdin for? We're gonna be

millionaires! We're gonna be selling to, like, five people that live down here, but we'll

be millionaires! Here comes the secret, oh, boy, oh, boy, oh, boy, oh, boy, oh, boy, oh,

boy! It's dark in here. I'll be honest, I don't know why I expected the lights to be

on. I should have known that Sans was very eco friendly. All right, so we finally made

it into Sans' room and, if you ignore the giant spinning tornado of physics defying

objects, there's nothing of particular interest here. No, this isn't the real secret. The

real secret is in the shed behind Sans' house, which the key also happens to unlock. And

when you go downstairs you'll not only find a picture from the end of the game that Sans,

for some reason, has in his possession, but there's also a time machine... and the blueprints

to make it, not that it matters. None of this stuff actually effects the game in any way,

shape, or form. Thank you, everybody for watching! I hope that you enjoyed this video. If you

did, please remember to like. Ike-ike-ike-ike *manical laughter* One-one-o-o-one. In our

number one spot-s-sp-spot-z-z-zer-- There is evidence of another being in Undertale

that hasn't been discovered. His name is W.D. Gaster also known as WingDing Gaster and,

subsequently, believed to be one of the third brothers to Papyrus and Sans. This is evidenced

by the blueprints written in a symbols you cannot identify in Sans' basement. Blueprints

for the time machine. *indistinct* Gaster has a message that can be found in the game's

code that is written in WingDings. When translated, it says this. It is believed that all of Sans'

powers come from Gaster's inventions. This power is so extensive that even if the player
