Wishful

Wishful is an evil unicorn that first appears in the episode: Pickles Potion Problem. In that episode, she captures Yimmothy, and convinces Crusher to turn evil. In the following episode: A New Threat, she has Yimmothy's UFO, and forces Crusher to attack Mochi, Pickle, and Kaos. She is defeated though. But just like Fat Panda, she will make her comeback.
