Mondo the Magical is one of the disguises of Jonathan Chiller. He first appeared in Heads, You Lose!, where he made Jessica and Ryan disappear and end up at the gift shop, where Jessica received her coin. He reappeared in The Horror at Chiller House, where he was Jessica’s helper after she, along with five other children, was called back to Horrorland.
