Jason Mantzoukas

Growth spurts, or the lack of it, add to the usual tensions faced daily by the middle schoolers of Big Mouth. Andrew (John Mulaney) struggles to fit in, while Nick (Nick Kroll) struggles to contain his raging hormones. Jessi (Jessi Klein) and Jay (Jason Mantzoukas) enter a rebellious phase. A classmate's blossoming figure sends the boys in their school a-stir and the girls into fits of insecurity. The Shame Wizard (David Thewlis), the sworn enemy of the Hormone Monsters Rich and Maurice (Nick Kroll) and the Hormone Monstress (Maya Rudolph), comes to town and piles on the torment the teenagers are already facing.

Sappy cards. Stupid clichés. And so much pressure. For Andrew, Nick, Jessi and friends, Valentine's Day is a total freaking minefield.
