Adventure Time Halloween Special #1 — Finn and Jake Face Their Fears in Jeremy Melloul’s First-Ever Spook
Finn and Jake sign up for a quest they didn't fully read the fine print on, only to find themselves trapped in a mysterious dungeon where they’ve become the very monsters they once fought. Jeremy Melloul and Adam Seats deliver OOO’s first Halloween special, a 48-page treat of body horror, familiar faces, and self-discovery.
There’s a special kind of magic in returning to the Land of OOO, especially when it’s wrapped in the crisp, unsettling energy of Halloween. Oni Press is serving up Adventure Time’s first-ever Halloween Special, and it’s the kind of standalone issue that lets creators stretch their legs without the burden of a continuous storyline. Jeremy Melloul takes the writer’s chair, bringing his knack for found-family dynamics, while rising star Adam Seats handles the art. It’s a spooky-sized 48-page special that feels like a warm blanket made of slightly eerie wool.
The premise is deceptively simple until you read the fine print. Finn and Jake sign up for a quest from the Adventurer’s Guild, assuming it’s just another day in the post-apocalyptic wonderland they know so well. But this dungeon is different. It’s alive, and it’s playing tricks. Before they can even unbuckle their swords, the landscape shifts, and suddenly the noble heroes are swapped into the bodies of the very monsters they’ve spent their lives fighting. It’s a classic identity crisis wrapped in fantasy, forcing our duo to navigate a world where they are both the hunters and the hunted.
What makes this issue a must-read is the creative chemistry between Melloul and Seats. You can feel the influence of Pendleton Ward’s original vision—whimsical, heartfelt, and occasionally deeply strange—but filtered through a modern lens that isn’t afraid to get a little dark. Seats’ art captures the grotesque beauty of the dungeon inhabitants while keeping Finn and Jake’s expressions painfully relatable. It’s a story about confronting the things that scare us, both literally in the dungeon and metaphorically within ourselves. It’s clever, it’s funny, and it’s genuinely haunting in the best way.
If you’re looking to round out your shelf with something that captures the spirit of the season, this is the one to grab. It’s a perfect entry point for new readers who want to dip their toes into the world of OOO without needing to catch up on decades of canon, and a nostalgic hug for longtime fans who miss the early episodes’ blend of adventure and melancholy. The Sean Dove cover variant is a standout, too—creepy, colorful, and instantly iconic. These move fast, so I’d suggest getting yours before the season passes.
