The three Goodfeathers are Bobby, Pesto, and Squit. Bobby is the big one with the soft voice. He is often needed to keep Pesto and Squit from killing each other. Pesto is the excitable one, with a hair-trigger temper. Squit is usually the one to set Pesto off, usually with some innocuous comment.

Sample exchange: (paraphrased)
Squit: "Wow, Pesto, that was really eloquent!"
Pesto: "What did you say?"
Squit: "I said, that was really eloquent."
Pesto: "Are you saying I'm some sort of pachyderm, with a long trunk and big ears?"
Squit: "No, man, I'm just saying that what you said was really eloquent!"
Pesto: "THAT'S IT!"
(Pesto proceeds to pummel Squit.)
