Jiff is a young boy whose soul awaits judgement in Purgatory.
Jiff was one of many souls to be given to demons by The Bosses off the record in exchange for control of The Pipeline to the real world. Jiff was saved from a Winged Demon by Peter Venkman, and later saved Venkman after he got captured in a Trap. Jiff used a rock to bash the Trap in. He escaped Purgatory with Janelle and the Ghostbusters to the real world. After a week, he and Janelle returned to Purgatory.
