Adventure Time is taking readers to an alternate universe, where fan-favorite characters Princess Bubblegum and Marceline get to experience college! It's the franchise like you haven’t yet seen it before.

In Adventure Time: The Bubbline College Special #1, by cartoonist Carline Cash, Princess Bubblegum takes her studies to Ooo University, where she experiences the highs and lows of pursuing a degree. However, her life will change when she meets the flying vampire Marceline, whom she feels an immediate connection to. While the comic remixes Adventure Time lore, it will feel fresh and familiar.

Adventure Time: The Bubbline College Special #1 features main cover art by Caroline Cash, with variants by Robyn Smith and Chloe Stawski (which is also available as a 1:10 black and white incentive variant). Check out the main cover art and text solicit below.
