Grudge is Vendetta's giant hamster fiend. He used to fill the role of Vendetta's sidekick and thug enforcer until he thinks that she doesn't want him anymore. Grudge grunts and growls to express himself. In the Making Fiends TV series, it is expanded more on his feelings for Vendetta, showing that he really does care about her and her safety. Vendetta usually referrs to him as "Hamster", whereas Charlotte is the only person to date who refers to him as "Grudge". He is voiced by Peter Merryman.
Buttons was Charlotte's pet hamster, and her "favorite hamster in the whole world". He resembles a miniature Grudge. According to Charlotte, Buttons likes peanuts and buttons. His prominent feature is the high-pitched squeal he makes when he is scared. He is sometimes seen to be scared of Charlotte as she treats him more like a plaything than a pet and that's why he ran away. He is voiced by Amy Winfrey.
