The challenge was

Create an original t-shirt design inspired by Adventure Time.

Vampire kick!

It’s been ages since we invited you to submit designs featuring Finn, Jake, and the gang, and our Adventure Time tees could use a little company. So to celebrate season 7, we want you to take a trip to the weird, wonderful world of Ooo.

Season 7 kicks off with a multi-part series all about your favorite guitar-wielding half-vampire, Marceline. When one of Princess Bubblegum’s experiments goes awry, ghosts from Marceline’s past invade Ooo—and things get spooky. Delve into the freaks and friends that surround the Vampire Queen to create an all-new Adventure Time tee that’s totally mathematical (no math required).

Keep in mind:

  • Designs must be your original artwork.

  • You may use any characters Adventure Time, but we encourage submissions based on Marceline and her underworld.

  • Mashups, parodies, or references to any non-Adventure Time characters are not allowed.

  • No adult references (sex, drugs, alcohol, violence, profanity, gambling, etc.) allowed.
