Grudge: (Voiced by Peter Merryman) Vendetta's giant hamster fiend, mistaken for a bear by Charlotte and a dog by Mrs. Minty. Grudge does not speak, but rather grunts and growls, and is Vendetta's constant sidekick. He assists Vendetta in making fiends and giving threats to those who defy her. Vendetta almost never refers to him by name, simply calling him "hamster". Unlike most other fiends, he seems to actually care for Vendetta and her safety, despite her harsh treatment of him. Like Rubella and the cat fiend, he is also capable of eating inedible objects. In episode 18, Grudge is replaced by Rubella.
