Pesto is a short-tempered Goodfeather modeled after Joe Pesci's character, Tommy DeVito from Goodfellas. Pesto also has a sister named Sasha, who is Squit's girlfriend.
Pesto is very short-tempered. The running gag of the segments would involve in him taking Squit's innocent remarks as insults and asks him questions in an angry "Tommy DeVito-esque" manner, which then leads to him beating up Squit, usually causing Bobby to laugh his head off. That gag was inspired by Tommy and Henry Hill's (played by Ray Liotta) famous arguement in the film. He made a cameo in the Animaniacs The Video Game for SNES, outside of his game his personality is still the same, except that he will take almost anybody's innocent remarks as insults and then ask them questions in an angry "Tommy Devito-esque" manner, which then leads him to beat them up, with the exceptions of: Butterscott, Strawbetty, Gelatina, Apozzer and Twister. He's close friends with Twister Von Schweetz and Betsy.
Pesto is a purple, blue pigeon, while his head and tail are purple, his body is blue and he has a cream belly underneath his body. Pesto also has heterochromia, pink on the right and light green on the left eye.
