The Mad Doctor

On a stormy night, a tremendous clap of thunder jolts the sleeping Mickey Mouse (voiced by Walt Disney) awake. He discovers that his pet Pluto has been kidnapped by a terrifying figure clad in black. Braving the fierce winds, Mickey follows the trail, overcoming countless dangers until he finally arrives at the black-clad figure's castle. He cautiously makes his way through the castle, facing traps, disasters, and evil spirits one after another. It turns out the black-clad figure is a mad doctor who plans to surgically merge Pluto with a hen, then hatch eggs to produce puppies. The timid Pluto trembles in fear. Mickey finally breaks into the laboratory, only to be strapped to the operating table, facing the fate of dissection. Will he and Pluto ultimately be saved?
