Catnip is a Sanrio character from the 1987 "Hello Kitty's Furry Tale Theater." She played a lot of villainous roles such as Ebenezer Scrooge (A Christmas Carol), Darth Vader, Captain Hook, Ugly Stepsisters, Count Dracula (Dracula), Dr. Victor Frankenstein, etc. Catnip also made rude and unpleasant jokes and pranks to Hello Kitty and her friends such as My Melody, Chip, and Tuxedo Sam outside of the theater as well. A bulldog named Grinder was her henchman and she also had a mother named Fangora, who was even ruder. Catnip is also kind of tomboyish so a lot of male villains are behaviorally similar to her (she even had a fair share of male and female villain roles too). She was voiced by Cree Summer Francks.
- Catnip is also similar to Thaddeus while Grinder is also similar to Thor from the 2009 Phineas and Ferb episode "Thaddeus and Thor."
