BOO... FROM THE LAND OF OOO! ADVENTURE TIME’S FIRST-EVER HALLOWEEN SPECIAL IS HERE! From writer Jeremy Melloul (Dungeon Masters Guild) and rising star Adam Seats, noble heroes Finn and Jake enter their trickiest situation yet in this SPOOKY-SIZED 48-PAGE special that’s definitely a treat! After signing up for a quest from the Adventurer’s Guild without reading the fine print, Finn and Jake find themselves in a new dungeon — turning into some of its monstrous inhabitants! Stuck in strange bodies, fighting familiar faces, and attempting to get to the bottom of this mysterious place, can our dynamic duo best this unearthly dungeon or will they fall victim to the monsters within... and within themselves?
