The Adventures of Raggedy Ann and Andy S01 E07 The Megamite Adventure

Marcella's cousin David has a robot named Megamite, who gets whisked off into the parallel world with Raggedy Ann. When Cracklin sees Megamite has the power to transform water into silver, he steals the robot and dries up the reservoir of a village of pixies, risking widespread dehydration unless Raggedy Ann can recapture Megamite.
