Why did the showrunners end Big Mouth in 2025?

The groundbreaking animated series is an unabashed exploration of adolescence using a dash of humor and plenty of absurdity. It is loosely based on the childhood friends Nick Kroll and Andrew Goldberg’s experiences with puberty.

Big Mouth revolves around the students of Bridgeton Middle School - Nick (Kroll), Andrew (John Mulaney), Missy (Ayo Edebiri), Jessi (Jessi Klein), Jay (Jason Mantzoukas), and Matthew (Andrew Rannells).

The series highlights the challenges that come with the exploration and acceptance of one's body through the hormone monsters, the Shame Wizard, the Depression Kitty, Tito the Anxiety Mosquito, and the Lovebugs named Walter, Sonya, and Rochelle.

On June 11, 2024, Kroll spoke to The Wrap about his decision to end the acclaimed series after 81 episodes by saying:

"We didn't ever think this was a show that should go on forever... The themes of adolescence and change — it would be a disservice to continue telling these stories with no end because this is a moment in time in your life. We always knew that and wanted to not diminish the characters by keeping them stagnant. It’s been gratifying to try to complete those stories."

Kroll added that these characters could return in possible sequels in the future as there's "ample opportunity" to revisit them at later stages in their lives.
