Crabbit Familiar is Maja's companion and sidekick in "Sky Witch." He is sent to do the evil deeds throughout the episode. When Princess Bubblegum and Marceline first encounter him, he drops a feather that transforms into a likeness of Hambo. Princess Bubblegum recognizes the trap and throws her googoomamameter at it, causing the illusion to disappear and prompting wooden pikes to thrust upward out of the ground underneath it.
Later on in the episode, after shapeshifting into Hambo to trick Marceline, he fights her but loses badly. Battered and bruised, he tells Maja that he wants to give up working for her to take up dancing. Maja then chases him down the hall, zapping him with her magic.
Maja's Crabbit Familiar first appears as a black rabbit-crow hybrid, before taking on a human-like form in order to battle Marceline.
