Shroofle is based on a truffle (a type of gourmet fungi), it has a convex type of cap (head) and campanulate bell like type of arms. Its lower body has the appearance of it wearing a skirt, and has three spots on its body.
Spotted variants were hunted extinct long ago for their divine taste. Modern Shroofle lack spots and taste horrid.
Shroofle was added in the dex to be a Spinda replacement like with Acufront and its forms getting hard coded into the mon. However, the spot gimmick is currently not used because the devs thought it looked horrible.
Uh oh, they're removing Joke-ish trivia from the pages. This is it, guys.
Shroofle is a mushroom and a truffle, two types of fungi.
