They leave college with the appliances and Ratso, hoping to start a new and happy life. In the end, all the animals are adopted by new owners except Ratso, who Rob and Chris decide to keep as their pet. The Brave Little Toaster to the Rescue is the direct-to-video sequel to The Brave Little Toaster. The Brave Little Toaster Goes to Mars Sometime following the Master graduating from college and marrying Chris, Toaster and the others are at their new home as the Master and Mistress return, revealing them to be the proud parents of a new baby boy, whom Toaster and the other appliances warm up to, dubbing him the 'Little Master'. Wittgenstein restores Rob's thesis and is later sold to a museum to be upgraded with modern technology. Chris later replaces Radio's tube with a new one she found in Nome, reviving him. Later, they discover Wittgenstein and Radio in the basement. After discovering the appliances in the truck, Rob and Chris assume that Mack had also planned to sell Rob's stuff, but Rob wonders where Radio is.

They manage to lure the police in front of the truck and have him arrested. The appliances create a makeshift vehicle and pursue Mack's truck with Rob and Chris following them. The appliances and Wittgenstein alert Rob, his girlfriend Chris, and the guard dogs to Mack's scheme. The appliances replace the tube, and with its boosted power, Wittgenstein wakes up, regenerating all of his other tubes and destroying all the viruses within him. Guilt-ridden over condemning the animals to their doom at Tartarus Laboratories, Radio gives up his own tube, sacrificing himself. Wittgenstein does his best with all his might, but the virus causes him to blow his remaining tube, and he dies. However, when they come back with the tube, Radio and Ratso accidentally break the tube after an argument, and it seems that all hope is lost. In an attempt to revive Wittgenstein to his superior state, Radio and Ratso go to the college's storage building to find the WFC-11-12-55 tube. The appliances learn that, unless they find a replacement quickly, Wittgenstein's tube will blow and lead to his death. Due to being infected by a computer virus, the supercomputer reveals that he is living on one rare vacuum tube, the WFC-11-12-55. The appliances discover an abandoned old prototype TLW-728 radio named "Wittgenstein", all alone and run-down in the basement. Meanwhile, Mack, Rob's lab assistant, plots to sell the injured animals Rob had been tending to as part of his courses to a Santa Clarita laboratory, "Tartarus Laboratories". The appliances, along with a rat named Ratso, seek to help Rob by finding and reversing the effects of his computer virus, thereby recovering the master's thesis.

One night, while finishing a thesis, his computer crashes due to a computer virus. Rob McGoarty, the owner of the appliances who is referred to as "The Master", is in his last days of college and is working at a veterinary clinic.
