Big Mouth has returned to Netflix with its seventh and penultimate season, which means there's no time like the present for the Bridgeton Middle Schoolers who have been learning about their changing bodies and hormone-ravaged psyches for six seasons to level up to high school. A change like that brings with it all sorts of anxieties, inadequacies, and reasons to be indiscriminately horny.

As is the case every season, Big Mouth has added a bunch of new characters — one-offs and recurring — and cast some highly recognizable voices. And since there is nothing more frustrating than not being able to identify a voice in an animated show, then have the auto-play jump to the next episode before you can check the end credits to see who that voice was, we're offering you the benefit of our expertise. Here is the lineup for the new voices on Big Mouth Season 7, and which characters they're playing.

Billy Porter as Ocean

The Tony-, Emmy-, and Grammy-Award-winning performer joins the Big Mouth cast this season as Ocean, a high schooler who uses they/them pronouns and who gives Matthew (Andrew Rannells) hope that there might be queer people as fabulous as he is at his new school. Ocean is also big in the queer choir at the high school, which opens the floor for the kinds of musical performances Big Mouth is partial to.

Stephanie Beatriz as Lulu

Beatriz, who starred in Brooklyn Nine-Nine and provided the voice of Mirabel Madrigal in Disney's Encanto, stars as Lulu, a tough-as-nails mean girl at the high school. Lulu intimidates the hell out of Jessi (Jessi Klein), even as her gloomy outlook on life would seem to dovetail pretty well with Jessi's exterior pessimism.

Rosie Perez as Petra, the Ambition Gremlin

Andrew Glouberman (John Mulaney) needs some kind of direction in life that doesn't involve masturbating at the thought of… well, anything. Enter Petra, whom viewers of the Big Mouth spin-off Human Resources will already be familiar with. Petra is all about nurturing that drive inside people to succeed, and who knows what actual success might do for Andrew. Perez is an Academy Award-nominated actress famous for films like Do the Right Thing, White Men Can't Jump, and Fearless. She was recently nominated for an Emmy for her performance in the Max original series The Flight Attendant.

Randall Park as Pete, the Logic Rock

Pete is another character who was established on Human Resources before making the move to Big Mouth. Pete presents as a man with the big stone head of an Easter Island statue, which is supposed to represent his status as a creature of logic and good decision-making. With Caleb (Joe Wengert) — who is on the autism spectrum — seeing an increased presence in the Season 7 storylines, Pete is there to help him reason his way out of anxiety-spiking situations. Park is a comedic actor best known for his performances in ABC's Fresh Off the Boat and as Governor Danny Chung on Veep. Park and fellow Big Mouth guest voice Ali Wong starred in the Netflix rom-com Always Be My Maybe, and he's appeared in several MCU projects as government agent Jimmy Woo.

Zazie Beetz as Danni

While the Big Mouth kids are all preparing to graduate from Bridgeton Middle School, they'll soon be encountering new classmates at high school. Such is the case for Nick, who meets hot, perhaps diabolical Danni and is predictably smitten. She's voiced by Zazie Beetz, who came to fame with her role in Atlanta and most recently starred in Steven Soderbergh's limited series for Max, Full Circle.

Megan Thee Stallion as Megan the(e?) Hormone Monstress

If we're getting a new pubescent character, that means we're likely also getting their hormone monster. In the case of Danni, it means we're getting Grammy-winning rapper Megan Thee Stallion as the horny devil on her shoulder. Megan is currently in select movie theaters in Dicks: The Musical, so the Hotties are eating well this autumn.

Maitreyi Ramakrishnan as Marissa

New love interests abound in this season of new beginnings, which means Andrew gets to meet the pretty, sweet girl across the street named Marissa. She's voiced by Maitreyi Ramakrishnan, best known to Netflix viewers as Devi Vishwakumar in the recently concluded teen rom-com Never Have I Ever.

Padma Lakshmi as Priya

The course of true love never does run smooth for Andrew, so don't be surprised that his meet-cute with Marissa becomes significantly complicated after he meets Marissa's smoking hot mom, Priya, voiced by now-former Top Chef host Padma Lakshmi. You can know it’s Padma Lakshmi because the character looks exactly like an animated Padma Lakshmi.

Lupita Nyong'o as a Shame Wizard

This season, Big Mouth goes international with vignettes about the mortifying effects of puberty on kids in, among other places, Korea, Iran, India, Australia, Kenya, and Brazil. In the Kenya-set segment, Oscar-winner Lupita Nyong'o voices a Shame Wizard belonging to a young Kenyan girl yearning to get her life aboard a matatu party bus. Other voices featured in the international episode include Tony-nominated performer Robin de Jesus, who performs a song written by Lin-Manuel Miranda, and What We Do in the Shadows star Kayvan Novak.

Don Cheadle as Himself

It wouldn't be a season of Big Mouth if we didn't get a celebrity making a vocal cameo as themselves. This year, it's celebrated actor Don Cheadle, who voices himself, though to reveal in what context would be to spoil the fun.

Big Mouth Season 7 is now streaming on Netflix. You can join the discussion about the show in our forums.
