Cranky is a green squirrel with a dark yellow diamond marking on his head. He wears a red shirt. He can get angry easily, but can warm up to some friendly tree friends. But no matter his mood, he's always shown with an angry face. His only hobby is fishing, and he even dreams that he can get himself a rare one to keep. When it comes to dislikes, Cranky dislikes lazy people. He also dislikes overly-optimistic people, which is rather questionable. Other than those, Cranky dislikes superheroes of any kind, thinking that all of them are a nuisance.
- In Simpsons episodes, he takes place of Todd.
