Ms. May Dusa

Ms. May Dusa is a denizen of the Underground, like the rest of monsterkind, and she chooses to make her home in Waterfall. She's a frequent visitor to the Wishing Room, often waiting until no-one else is around to appear to make the same wish, hoping it might come true. She often braves the cold of Snowdin with her fire magic in order to visit the library, with the occassional pop in to Grillby's to keep warm and get a bite to eat.

She's rather shy around others because she has a hissy lisp and because she's fairly clumsy and doesn't want to make a fool of herself. (It's hard to hold things when you have snake tails for hands.) She also happens to have a crush on the shorter skeleton brother, and wants to invite him over for tea, though she hasn't quite gotten the courage yet.
