Netflix’s hit adult animated series about going through puberty, Big Mouth, had its Season 3 debut in early October, and the series already has a lengthy, hormone-fueled future ahead since it was picked up for Seasons 4, 5, and 6. There’s even a Human Resources spin-off in the works, so we can all expect plenty more Big Mouth episodes until at least 2022.
Big Mouth Season 2 raised the stakes of this weird universe by introducing the Shame Wizard, and Season 3 continued that trend with the Menopause Banshee. What could possibly come next?
Big Mouth is best known for turning uncomfortable concepts like hormones, shame, and depression into fantastical creatures, and it stars Nick Kroll as many of the characters with an all-star voice acting team that includes the likes of John Mulaney, Jenny Slate, Jordan Peele, Jason Mantzoukas, and Maya Rudolph.
Here’s everything we know about Big Mouth Season 4 (and beyond), from potential release dates and trailer news to what you should expect from the plot.
Is Big Mouth confirmed for Season 4?
Yes! In July 2019, Big Mouth co-creator Nick Kroll confirmed in a tweet posted to the show’s Twitter account that Netflix had picked up the series for Season 4, 5, and 6.
In an October 2019 interview with Esquire, Jay Bilzerian voice actor Jason Mantzoukas confirmed he’d already recorded his lines for Season 4. “I wish I could even tell you some of the [Season] 4 stuff. It’s so good. I’ve just recorded all of Season 4. I can’t remember what is 3 and what is 4.” That’s a strong indication that production is already very far long on the new season.
When is the Big Mouth Season 4 release date?
Season 1 was released September 29, 2017 on Netflix, with the second season arriving on October 5, 2018. Especially because Season 3 was released on October 4, it seems reasonable to assume that Season 4 will be released either on Friday, October 2, 2020 or the week after on October 9.
Is there a Big Mouth Season 4 trailer yet?
There’s no trailer for Big Mouth Season 4 yet, and the Season 3 trailer didn’t arrive until mid- to late-September before the new season’s release. If that release schedule continues, then we can expect a legit trailer sometime in September 2020.
Season 3 did include a Valentine’s Day special, however, so it seems possible that Big Mouth might have another holiday special that’ll be released sometime over the next year. Could that include a Christmas special? New Year’s? Another Valentine’s Day special? Given the early renewal for the series ahead of Season 3’s release, any of these seem possible.
How did the end of Big Mouth Season 3 set up Season 4?
The last few episodes of Season 3 shattered the core friend group of Big Mouth.
After Nick kissed Missy in a later episode and even went on a date with her, Andrew discovered and took the betrayal really hard. It drove a wedge so big between the former best friends that in the finale, Andrew essentially broke up with Nick and didn’t go to summer camp. Similarly, Missy finds herself ostracized from both boys when Nick realizes he doesn’t want to date her. kissing Nick also triggered a breakup between her and Lars.
Another dramatic change for the series is that Jessi’s mother decided that they were moving to New York City, leaving Missy with one less female friend. Matthew also expresses disappointment at her leaving, but during the superhero episode, Jessi’s truth powers reveal that he isn’t all that worried because he has his new boyfriend Aidan.
The only positive surprise comes from Jay, who uses his manic energy and everything he learned from living with Birch family to refurbish the Bilzerian home and bring something resembling love and joy to the household.
It feels like nothing will ever be the same when Big Mouth returns in Season 4.
What will happen in Big Mouth Season 4?
Based on how things left off at the end of Season 3, we’ll probably get a time jump to reach Season 4. Things ended at the start of summer, so it seems logical for things to pick up again at the start of the school year several months later. Jessi will probably be adjusting to life in the city, meeting new friends and dealing with the awkwardness of trying to fit in at a new school.
My own personal wish is that Nick hits a bit of a growth spurt and has an amazing time at summer camp. Maybe he even returns with a girlfriend? He and Andrew will still be on rough terms going into Season 4, but they’ll likely spend the season inevitably becoming close friends once again.
Will there be a Big Mouth Season 4 crossover with Human Resources?
During the New York Comic Con 2019 panel ahead of Big Mouth Season 3’s release, Nick Kroll teased that the show might return to the world of the hormone monsters in future seasons, and later on, he confirmed that a spinoff called Human Resources was in development.
“It’s about the monsters and the creatures who manage people,” Kroll said to the enthusiastic crowd at NYCC. “We’re excited to tell a lot of different stories, not just about puberty, but about all stages of life.”
He also confirmed that they’d start production on the new series only after finishing Big Mouth Season 5, so it’s possible we might get a backdoor pilot episode of sorts if the show revisits that world like it did in the Season 2 finale.
Big Mouth Season 3 is now available to stream on Netflix, and Season 4 is expected sometime in 2020.
