Strange Cake
From the Super Mario Wiki
In the game Paper Mario, a Strange Cake is made with Cake Mix and a Strange Leaf, but its purpose is just as strange as its appearance. When eaten, the cake will make Mario either Electrified, Invisible, or Sleepy. Love Pudding in Paper Mario: The Thousand Year Door, has the same effect. Also in this game is the Peach Tart. It has one difference: the invisibility possibility is replaced by Dodgy.
