Cake is a slice of chocolate cake that blushes a lot. He has a dollop of white meringue on top of his head near a smudge of pink frosting. In case you're curious, that meringue is indeed squishy, which entices others to sit on him. Much more than other characters with their own kind, Cake strongly empathizes with inanimate cakes, becoming excited when they're celebrated and upset when they're eaten.

Cake relies on others for emotional support, especially Loser.
