My take on undertoad:

Undertoad: StarBound

I'm still working on it. But I think wario and waluigi fit sans and papyrus more, and Mario and Luigi more so fit undyne and alphys.

Insanity sans...

UnderSwap Sans and Dust Sans!

So I'm making an AU called TS!Hardswap.

(Super original totally)

Here's sans and totally not sans.

Funni ghost rider finger wag.

TS!HardSwap Papyrus design

on days like these...

kids like you...

should be learning how to...

DRAW!

OH SHIT WHAT THE FUCK IS THAT THING-

oh... thats...

That's a new bullshit au I made called TRUE!Swaptale...

I NEED A COOL NAME FOR TS!HARDSWAP CROSSBONES.

Human... I Rember you're DISTRUSTS...

Egg.
