Rosella, in an effort to retrieve Iggy for the Gravedigger who had saved her life, gave the Weird Pet to the Ghoul Kids. Distracted, they gave Iggy a chance to escape. He leapt from the Pumpkin House to Rosella. She brought him back to the Gravedigger, and Iggy immediately got back to work.
Iggy is a character and an inventory item that appears in King's Quest VII: The Princeless Bride.
