Trailer: ‘Big Mouth’ returns December 4 new guest stars and a focus on teen anxiety

The show addresses the issue of Jenny Slate voicing a Black character in early episodes

Netflix’s Emmy-nominated animated hit Big Mouth is set to return December 4 for its fourth season.

This season focuses on anxiety; the anxiety of growing up, of figuring out who you are, discovering yourself, accepting yourself. The season starts at summer camp before our gang heads to 8th grade. Maria Bamford descends as Tito the Mosquito, the anxiety ridden insect who targets all our favorite kids. As the season progresses, we meet Zach Galifianakis’ Gratitoad, who is there to help our crew cope with their anxiety and not let it completely own them.

Big Mouth continues to explore human sexuality and everything around it, including racial and sexual identity, love in all its forms, and having “The Hugest Period Ever.”

Additional guest stars include: Seth Rogen, Josie Totah, Lena Waithe, Quinta Brunson, John Oliver, Sterling K. Brown, Paul Giamatti, Maya Erskine and Anna Konkle. As previously announced, Ayo Edebiri has been cast as Missy, replacing Slate, and will first be introduced during the penultimate episode as her character continues to evolve. She will continue to voice Missy in the final episode and for future seasons.
