Matpat, I LOVE UR vids! Keep on keeping on!😜
This video actually made me want to play Undertale again to discover the true lab (I only played it once on a neutral [pacifist in the first run is neutral])
Junior GhostCorn

Mat Pat your videos educate me I spent my whole spring break watching your videos I learned a lot just from watching a week of your videos like I learned a lot about dopamine and multiverses.
Ok Mat Pat, even though you'll never read this, I have another Gaster theory. So in the last episode you said Gaster could be a FATHER. So if he really is a father, Sans and Papyrus are his sons, right? But how do you get sons? You need a MOTHER. Ok, so... Where is the mom? Well, we learn in the beginning of the game the monsters and humans had a war with each other. And that there's a Royal Guard. SOOOOOOO... Could Sans and Papyrus's mom been in the Royal Guard, thus being in the war? And died? And to this pressure, instead of Gaster "accidentally" falling in the determination extraction machine, could he have thrown himself in there on purpose? Hmmm? Oh! And a question. How did Gaster get holes in his hands? PLEASE NOTICE MY QUESTION AND ANSWER IT IN YOUR NEXT UNDERTALE VIDEO.

I'm looking for the comment that's ask how do you get your Undertale cameo
Mettaton Leg
For those of you who didn't get the joke in the beginning, a humorous is an arm bone. Skeleton pun
Just a Really Random Person
Oh my gosh, this is SO weird. A few weeks before this, I started thinking about gaster, and his melted face. I thought, " Ohmygoshwhatifgasterisanamalgamateohmygosh". I then dismissed myself and the next week, I saw what my wonderful MatPat had uploaded. (You have no idea how long I happy danced)
sans the skelington
At the beginning those were very sansatioal puns you had there
Boston Bubbles
How can Gaster ask Sans and Alphys, "what do you two think" if Gaster is supposedly both Papyrus and Sans?
themoocow rockyisawesome
like if MatPat is awesome and #NoHate
Jeffrey Graves
omg i just had the best theory ever! ness is sans and papy then sans and papy melted into each other then gaster was born!!!!!!!!
Makmak0403 A
and sixbones was accidently created and a amalgamate of sans and papy
Makmak0403 A
in a vid a story of how sixbones was created had alphys says entry number blank

MATPAT what if "skeletons" in undertale have to be a human and then die or run out of determination and usually they loose there memory but sans dident and he wants to be human agien whitch is why he hates humans becouse mabby a human killed him and paps
LogantheSlayer 1
It's like the therory that gaster is sans and paps dad to a hole new level
LogantheSlayer 1
1:48 TO THE PATCAVE!!!!!!!!!!!
Where does the word search come in
Gaster means fright or scare
Desirae Wallis

VzFly Play
это не gaster это последователь.
Gaster created sans and papyrus undertale files says "gaster is the dad of" then the text was unable to read

So... Gaster is sans but Sans in Nes. So basically you're saying that Gaster is Nes. *MIND BLOWN*
Guys I have a theory. There is another character that doesn't use capital letters when speaking who I find slightly more likely to have written the lab entries. Napstablook. Notice that one of the messages in lower-case says that they are worried that Mettaton will leave them. Why would Sans be worried Mettaton would leave him. Napstablook has a very good reason to be worried about Mettaton leaving. I conclude that Napstablook just might have some kind of connection with Gaster or at least with Alphys and the True Lab. Like so MatPat can see. :-)
