Wendy

Wendy is a ghost (voiced by Kate Micucci) that first appears in "Heat Signature". She, with Booboo and Georgy, are friends of Marceline. The three help Marceline prank Finn and Jake. When the pranking goes too far, the three ghosts beat up Finn and Jake, then trick them into falling off of a building. They then try to suck Finn and Jake's guts. This shows that the ghosts are cold and have a dark type of humor, almost like Marceline. However, unlike Marceline, they do not respect Finn and Jake.

Appearance
Wendy, like her fellow ghosts, is a pale bluish, semitransparent being. To show her femininity, she has ghostly bosoms. She can grow to extreme sizes and grow tentacles to suck out peoples' guts.

Personality
Wendy doesn't care about anyone still alive but seems to like the undead. She is a carefree ghost and is an easily angered person.
