Donald and Pluto.Donald is a plumber fixing pipes in the basement of a house (presumably Mickey's house, since Mickey is mentioned on the title cover of the episode). Donald first has trouble with pulling his hammer off a magnet, which it gets stuck to. When he unscrews the lid covering the pipe, water spurts out and hits Donald in the face, angering him. To stop the flow, Donald uses the magnet to pull a larger hammer toward himself, which he uses to put on another lid to the hole. In doing so he accidentally wakes Pluto and later accidentally pulls Pluto's bone away from him. While Pluto wrestles with the magnet to get his bone back, he swallows the magnet and gets his bone stuck to his bottom. As he fights to get the bone, he tumbles into the pile of furniture Donald is standing on, causing Donald to come crashing to the ground. Pluto eventually runs into the kitchen and the magnet inside him causes many cooking items to be pulled onto his rear...
