You Don't Know Undertale

Things you probably missed, overthought or didn't know about Undertale. This is a fanmade blog and I do not own anything of Undertale.

Hello!!

I haven’t touched this blog in a while, and probably won’t ever any time soon. Sorry to disappoint any active remaining followers on this blog, but hopefully you’ve learned something new.

I, myself, am no longer interested in looking for undiscovered UT mysteries, mainly since I’m assuming all has been found by now. However, I have come across a secret you may have actually missed, and a lot of people are unfamiliar with this one: Toriel’s voice heard within an echo flower. Consider this the last youdontknowundertale post as of 2018 and beyond.

Thank you for your support and discoveries and perhaps we may cross paths again in the future. If you’re interested in humor, animals, cartoons and anime, feel free to check out my main blog.

Who knows, perhaps another excellent game one day with many (and I mean many) more discoveries to be found may peak my interest. Who knows?

I wish you all a lovely year and for those to come. One again, thank you for supporting youdontknowundertale.

Hiatus

Lately, I haven’t been discovering too many things that would seem unusual with Undertale content to its fans. So I am going on a slight hiatus to do some more research with the game and its files. Otherwise, I’ll be living my casual life with my main blog.

* (Knowing that one day this blog will return with more content you’ve never known about fills you with determination.)

In Debug mode, moving at specific times (triggered by tapping F10) can remove Papyrus’ font while he speaks.

Even in debug mode, there is no actual evidence that the blue door behind Sans has any purpose with the gameplay.

In the foggy room in the True Lab, the fridges have different descriptions. One of them being Snowdrake, and the second describing “the shape of a man”.

It’s unknown what/who it’s describing.

Unused ‘SPELL’ sprites.

If you choose Gaster’s Theme in the Sound Test, you cannot choose another theme afterwards.

Holding the up key the entire time during Sans’ first hang-out results in Sans walking off screen. He stays off-screen until you visit him back at Waterfall.

In the long room in the RUINS, Toriel asks you to wait where you are until she returns. If you do this instead of exploring the RUINS, you will get a phone-call from Toriel or a “small, white dog” every 3-5 minutes. (In order for this to trigger, you cannot access your inventory, nor move. Moving will deactivate this secret.)

Hope you’ve had a great year everyone, see you all in 2016! 🎆

Attempting to escape Papyrus’ puzzles along with Sans’ puzzles results with extra dialogue given by Papyrus.

These logs possibly belong to Gaster, knowing that he was the one who created the CORE.
