The Dancing Rats are a duo of theatrical rodents that reside at a garbage dump and appear in the episode "The Nutcracker". They wanted to make a stew out of Eustace and Muriel, but were thwarted by Courage and his nutcracker.
While browsing through the dump, Courage and his owners get locked inside. As that happens, Courage finds a nutcracker toy he cherishes. Later that night, two rats who ironically dance in ballet capture Eustace and proceed to chase after Courage and Muriel, dancing to music from the Nutcracker, though with the help of the nutcracker toy, Courage with Muriel kept on escaping. Later, Muriel is also captured and Courage with his toy head off to save his owners from the dancing rats.
