When Daggett is held captive by three singing river rats, Norbert must do what he can in order to rescue Daggett and ultimately get rid of the rats infesting their home. However, Daggett soon starts to snap after being forced to listen to their horrible music.
- The Rat Pack - The Pack Rats who steal the Beavers' dam are based on the famous group of entertainers from the 1950's and 60's. Rikki the Vermin, the bigger, white-haired rat is based on Frank Sinatra; Manicoti, the red-nosed rat always seen with a "drink" is based on Dean Martin; and Ratatat, the darker-colored rat in the pink shirt is based on Sammy Davis, Jr.
- Tasmanian Devil - After Daggett gets infested with spiders, he acts like the Looney Tunes character.
