American animated musical films based on the 1980 novel of the same name by Thomas M. Disch and produced by Hyperion Pictures.
Toaster is the leader of a gang of appliances consisting of a radio, a lamp named "Lampy", a blanket named "Blanky", and a vacuum cleaner named "Kirby" who belong to their "master"; a young boy named Rob. They wait every day at Rob's cottage for his return with an increasing sense of abandonment, which causes Blanky to hallucinate about finally seeing Rob coming back. On the second day of July, the appliances are devastated to learn that a real estate broker is selling the house. Not wanting to accept the fact that the Master would abandon them, Toaster decides that the group should head out and find Rob. The appliances connect a car battery to an office chair pulled by Kirby and set out into the world, following Radio's signal broadcast from the city where Rob has moved to.
Rob McGoarty, the owner of the appliances and whom they refer to as "The Master", is in his last days of college and is working at a veterinary clinic. One night, while finishing on a thesis, his computer accidentally crashes due to a terrible computer virus. The appliances along with a rat named Ratso seek to help Rob by finding and reversing the effects of his computer virus, hence recovering the master's thesis. Meanwhile, Mack, Rob's lab assistant, plots to sell the injured animals Rob had been tending to as part of his courses, to a place called "Tartaras Laboratories," the same facility that Sebastian, an old monkey, was sent to when he was just a baby. When the appliances discover an old TLW-728 prototype supercomputer named Wittgenstein abandoned, all alone, and run-down in the basement when transistor was invented. Due to being infected by a computer virus, the same one that affected Rob's dorm room computer and the one in the vet's clinic lab when Wittgenstein tried to contact them earlier, the miserable supercomputer reveals that he is living on one rare vacuum tube, the "WFC 11-12-55" (A reference to the producer and screenwriter, Willard Carroll, and his birthdate, November 12, 1955). The appliances learn that unless they find a replacement quickly, Wittgenstein's tube will blow and lead to his apparent death.
Now being married anew and having moved to Albert Einstein House, which is a house formerly owned by Albert Einstein, Rob and Chris have an infant son named Robbie. At first the appliances all fear that their masters will pay more attention to him but later grow accustomed to him. One night, Toaster awakes to find the hearing aid in the attic receiving a message which appears to be transmitted from space. The next morning, Toaster informs the other appliances and Ratso, the family's pet rat, of the events occurring the previous night, leading to the appliances and Ratso agreeing to carefully watch the junk drawer in case of Hearing Aid suspiciously escaping again. The following night, Hearing Aid escapes from the drawer and to the attic once more. Robbie, awakened by the sound of the transmission, climbs out of his crib and follows Hearing Aid. The appliances awaken, find Robbie going up the stairs and pursue him, leading them to enter the attic just as a beam of light appears. The shocked appliances pursue Hearing Aid, but in spite of this, Robbie is beamed into space. After grilling Hearing Aid and learning that Robbie has accidentally been transported to Mars in his place, the appliances contact Wittgenstein, an old supercomputer and friend from their days in college, for advice by connecting a computer to a security camera in the museum that acts like a phone. The appliances, as per a plan by Wittgenstein, create a makeshift spacecraft with the ceiling fan, a laundry basket, the microwave, and microwaveable popcorn as fuel (Calculator is also provided with the required data to be their navigator) and launch themselves into space, leaving only Ratso to prevent two baby monitor intercoms from alerting Rob and Chris. During their flight through space, the appliances meet a pack of sentient balloons who have been let go by human hands and now float endlessly through the cosmos.
