Big Mouth is about to say farewell with its eighth and final series, one of the big TV moments coming this summer. And in the trailer, things are as awkward as puberty can get.

As Maury the Hormone Monster (Nick Kroll) says, "It's the end of a very gross era."

In Season 8, the Bridgeton teens (Kroll, John Mulaney, Jessi Klein, Jason Mantzoukas, and more) tackle another round of adolescence with their supernatural aides, and judging by the video above, they've still got some horrendous, wondrous, perpetually terrifying growing up ahead of them.

Luckily, there's a host of guest voice stars to enjoy along the way, including Cynthia Erivo, Holly Hunter, Keke Palmer, Steve Buscemi, Quinta Brunson, Kristen Wiig, Ali Wong, Billy Porter, Natasha Lyonne, Nathan Fillion, Thandiwe Newton, Aidy Bryant, Stephanie Beatriz, Chelsea Peretti, Rosie Perez, Lena Waithe, and more.

Big Mouth Season 8 premieres May 23 on Netflix.
