Jimmy Pesto has seen less prominence in Season 2 as a major character to the plot, but appears in Burgerboss when Bob tries to beat Jimmy's high score on a video game when he leaves the initials to say "BOBSUX". In Tina-Rannosaurus Wrecks, Jimmy appears when he calls Bob to tell him that it was his parked car that Bob hit in the parking lot. While Bob doesn't want to sound irresponsible as a parent, he doesn't tell him that it was Tina driving the car.
In Full Bars, Jimmy Pesto gives the trick-or-treating Belcher kids oyster crackers. In The Deepening he is seen attending the block meeting in Bob's Burgers. Another non-speaking appearance for Jimmy Pesto is in the final moments of Nude Beach where we see a shot of Jimmy inside his restaurant.
