Fionna and Cake have finally gotten their own Adventure Time spinoff! We’ll see them whisked off to the candy-colored Land of Ooo, where they’ll need to persuade the former Ice King to help save their world. Below, we explain how to watch Adventure Time: Fionna and Cake online from anywhere with a VPN.

Adventure Time: Fionna and Cake streaming details

U.S. release date: Adventure Time: Fionna and Cake premiered Thursday, August 31 exclusively on Max.
AU release date: Friday, September 1 at 8 a.m. AEST on Foxtel Now and Binge.

Adventure Time: Fionna and Cake is the third series in the franchise. These characters started life as a gender-flipped version of Finn the Human and Jake the Dog, and thrilled viewers so much that they appeared in multiple episodes across the show’s 10-season run.

Madeleine Martin, Roz Ryan, and Tom Kenny (of SpongeBob SquarePants fame) are back as the voices of Fionna, Cake, and Simon Petrikov respectively. Their animated avatars will encounter many familiar faces from the original series, alongside lots of wacky new beings ready to enliven their world-hopping travels.

The series begins with Fionna and her cat being dragged from their reality into the multiverse. They’ll reunite with their former adversary the Ice King/Petrikov, an older version of Finn — now all hirsute and studly — and his dog Jake, all of whom are at Fionna’s disposal to help defeat a new world-ending villain.
