Synopsis by Hal Erickson
Here's the obligatory Irwin Allen "mad toymaker" episode, which begins when the Celestial Department Store ordering Machine malfunctions (again!) and Dr. Smith (Jonathan Harris) is turned into a toy clown. Disaster will befall everyone else unless John (Jonathan Harris) and the Robot can rescue Smith, who along with Will (Billy Mumy) is trapped in a fourth-dimension toyshop run by an elderly artisan (Walter Burke) who doesn't recognize his guests as human. Fritz Feld returns as the imperious Celestial Department Store head man Zumdish ("Pop!").
