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!").
