Big Mouth is an American adult animated sitcom created by Nick Kroll, Andrew Goldberg, Mark Levin, and Jennifer Flackett based on Kroll and Goldberg’s teenage years growing up in the suburbs of New York City.
The series follows a group of 7th graders, including best friends Nick Birch and Andrew Glouberman, as they navigate their way through puberty with struggles like masturbation and sexual arousal all in the suburbs of New York City. Acting as over-sexualized shoulder angels are the hormone monsters: Maurice (who pesters Andrew and Matthew and occasionally Nick), Connie—the hormone monstress (who pesters Jessi and Nick and occasionally Missy) and Mona (who mainly pesters Missy). Throughout the series, the kids interact with people and objects who are often personified and offer helpful, yet confusing, advice in their puberty-filled lives including the ghost of Duke Ellington, a French-accented Statue of Liberty, a pillow capable of getting pregnant, a bar of Adderall, and even Jessi’s own vulva. They seek out their destiny as puberty destroys them mentally and physically.
According to Screenrant “Season 4 will see Jessi, Nick, and Andrew going to camp, where Nick and Andrew’s friendship will continue to crumble. In addition to that, Jessi will have to deal with adapting to a new city and with more changes in her body, while Missy goes through a makeover. The group will also come across Tito, the Anxiety Mosquito, who will put their worlds upside down. Big Mouth season 4 will see the return of the main cast and will welcome new voices, ready to join the crazy ride that is puberty. Here’s the cast and characters guide for Big Mouth season 4 and what the voice actors look like.”
