"...I'll deal with Undertale later...

I don't want to take the credits for this because i don't know if i'm the first to make it.
It's strange that no one have thinked of an error version of Underswap (At least when i searched i didn't find any drawing/concept of him).
So if in Undertale Sans is the "main" Error then in Underswap it must be Papyrus and... there it is!
Also this is my first digital drawing so forgive me for some mistakes.
