What time is it? Why, time for the very first Adventure Time: Explore the Dungeon Because I Don't Know! trailer, of course. The isometric hack-and-slash co-op dungeon crawler from WayForward features the voice talents of John DiMaggio, Tom Kenny and Jeremy Shada, all of which are present to varyingly belligerent degrees in this first look at the game.

Kenny, the voice of the Ice King and everyone else from your childhood, describes Princess Bubblegum's Secret Dungeon as more of a "fungeon," meanwhile DiMaggio (Jake the Dog) seems mostly offended that someone is talking to him in the first place. The single most important takeaway from this, however, is that Cinnamon Bun is a playable character in all his awkward, uncomfortable glory.

Adventure Time: Explore the Dungeon Because I Don't Know! is headed to Wii U, Xbox 360, PlayStation 3, PC and 3DS sometime this fall.
