While Mickey visits a zoo, a little seal stows away in his picnic basket and travels to his house with him. Pluto discovers the creature, but Mickey can't understand what his dog is trying to tell him and eventually kicks him out of the house for making a mess. Later, Mickey unknowingly shares his bathtub with the seal for a baffling bath. Once Mickey finally discovers the creature, he and Pluto take him back to the zoo, but the seal and all his seal friends beat them back to their house to take over Mickey's bathroom.
