Viruses

The Viruses are minor antagonists from The Brave Little Toaster to the Rescue.

Role in the film
They appear during the "Chomp and Munch" sequence as they plague Wittgenstein by destroying his inner tubes and circuitry while singing the chorus part of the song. When Wittgenstein is later revived by Radio's WFC 11-12-55 tube, the viruses become destroyed (though before that includes a few remaining ones, they form the word "Yipe!") and are not seen again throughout the rest of the movie.
