No one knows what Puffball is. She's pink, fluffy, and round. Whatever she is, she can fly, barf rainbow substances when distressed, and change colors when she talks. Other than that, it's anyone's guess.
Puffball is self-indulgent and will do anything just for fun. Once, she built a stack of forks with some friends just to knock them down. When asked to keep a couple of cakes safe, Puffball ate them when no one was looking. She usually goes along with whatever her best friend Fries says.
