Pesto is a short-tempered Goodfeather pigeon, modeled after Joe Pesci's character Tommy DeVito from the film Goodfellas. The shortest of the trio, he is haughty, loud and openly hostile to everything around him, ready to go off at a moment's notice. A running gag of the segments involves him taking Squit's innocent remarks or compliments as insults and asking him questions in an angry "Tommy DeVito-esque" manner, which leads to him beating up Squit, usually causing Bobby to laugh his head off, but sometimes Bobby tries and stops Pesto from abusing Squit. The gag was inspired by Tommy and Henry Hill's (played by Ray Liotta) famous argument in the film.
Like Dizzy Devil, Pesto also has heterochromia, with a pink right eye and light green left eye.
Pesto has a mother, whom resides in Miami Florida. She eventually remarries to a much-younger seagull, Steven Seagull, whom Pesto was initially openly hostile towards but eventually warmed up to. Pesto also has a similarly ill-tempered sister, Sasha, who is ironically Squit's girlfriend.
