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.

UnderSwap Sans and Dust Sans!

Yo, long time no see, I'm still alive btw. So, I'm a bit late to being on here for the Undertale 10th anniversary... Sorry about that, I was just a bit homestuck.
