Ever since the official underfellx post (right image) I've been going nutty...I would let him ball (Is aware he'll fail miserably) <3

POV: He becomes a babbling idiot around you (or your character)

(It’s 2 AM & this doodle is funny to me at the moment- I am randomly feeding the Fell simps & yumes)

A doodle of a nervous Fell Sans sweating profusely as he fumbles his pick up line to an embarrassing degree. “Did heaven fall- SHIT- Did you heaven? Fuck- Wait- Not like- As in ‘Fuck You’, y’know? …. Y’know what?- Nevermind-“

Yumeship comic I finished last night XP for context it’s when they first meet and because the cat dude (Prince bloodmoon) is a self insert he has the same sensory issues I have irl. #yumeship #dragonfell #underfell #undertaleau

TADA! Last member of the Gaster family aka Wingding’s (William’s) wife Rosé! I do plan on doing a sort of family portrait or something eventually- btw her dragon form is concept and not canon. It exits to tie some design choices on my part together. #undertaleau #underfell #dragonfell

I don’t think I ever shared these? Drew them not long after the last Undertale anniversary stream. Still love these wannabe edgy guys
