Wishy appears to be a children’s drawing, with a rainbow body, a heart/star on either side of his face, and a crown.
Like Ice King's crown, Aquandrius, and Prismo, Wishy can preform Wish Magic. He is able to preform any wish that the user of the Demonic Wishing Eye desires. Unfortunately, once he grants the user their wish, he takes a piece of their soul.
- His crown and staff indicate that he might be a king of some sort.
