Finn and Jake are back for more Adventure Time.

Adventure Time is set in the Land of Ooo and is a coming-of-age fantasy story in a world that forms after a devastating nuclear apocalypse. Mutated life forms roam the world as Finn the Human and magical shapeshifter Jake the Dog roam the land for adventure and fun quests. The flagship series ran from 2010 to 2018 and was a huge success, spanning multiple spinoffs and appealing to all ages.

A new trailer has been released for the spinoff, Adventure Time: Side Quests, which shows the origins of Finn & Jake, as the main voice actor for Finn has been recast. Sasha Knight is now playing the role of Finn the Human, alongside John DiMaggio as Jake the Dog, Tom Kenny as the Ice King, Hynden Walch as Princess Bubblegum, Olivia Olson as Marceline, and Niki Yang as BMO.

"Adventure Time captivated audiences with its heartfelt storytelling, playful humour, and richly creative world. Adventure Time: Side Quests builds on the spirit of the early seasons, delivering lighter, self-contained adventures.

Designed to introduce a new generation of fans to the land of Ooo, whilst giving existing fans more of what they love, the series brings standalone, silly quests and playful challenges - celebrating the joyful chaos of Finn and Jake’s adventures."

Disney+ and Hulu have also announced the new series will be released on June 29 as a companion show to the original Adventure Time series. Showrunner and executive producer Nate Cash (known for SpongeBob SquarePants) addressed the new series announcement and stated that "Making Side Quests felt like making the original Adventure Time, which felt like hanging out with art school buddies making professional cartoons. That sounds like a big sandwich of feelings, and it was! You're going to love these NEW adventures with Finn & Jake!"

Another celebrated Adventure Time spinoff is Fionna & Cake, which is a series aimed at adults who grew up with the original series. It turns the tables and was originally made by artist and animator Natasha Allegri in a series of gender-bent webcomics. Ice King is shown to create a fanfiction where Finn and Jake are actually women, and it tackles heavier and more mature themes offering harsh realities of life through fun animation.

Adventure Time: Side Quests will be arriving on Disney+ and Hulu on June 29.
