Donald receives a package in the mail containing a hypnosis kit with a pair of goggles. He decides to test the goggles on Pluto. He hypnotizes Pluto to think he's a variety of animals—a mouse, a turtle, a chicken—and each time Pluto starts behaving like the animal, even partially taking on its form. While in his chicken form he gets into a fight with a rooster, so Donald hypnotizes him to think he's a lion. Pluto becomes ferocious and starts attacking the rooster, and the two run into Donald, inadvertently causing the goggles to shatter. Pluto chases Donald, now unable to control him, back to his house and wrecks much of the place. They both end up breaking through the rooftop and running into midair, before plummeting violently to the ground, knocking Donald unconscious and returning Pluto to his normal self. Pluto licks Donald's face to wake him up, but thinking he's still in his lion state, Donald frantically rushes away. Pluto Fourth wall with a confused expression.
