When a clown shows up at Zeke's birthday bash, Zeke's friends aren't exactly tickled pink. They think clowns are kid stuff. But when Idris Zanzibar McFloot makes a baseball cap totallyá disappear , Zeke is dying to find out how he did it -- so he becomes the clown's assistant.

Before long, Zeke realizes he's in over his wig. The baseball cap was just act one of Idris Zanzibar McFloot's performance. Up next is the Box of Doom -- and if it works, Zeke and all of his friends will be lost inside it...forever! Can Zeke stop clowning around before he dies laughing?
