Peppermint Butler fans, take note: You do not want to cross Princess Bubblegum's trusted servant by forging concert tickets. Though it may seem harmless to pick up tickets to see the Land of Ooo's most popular rock band from a seedy stranger in a dark alley, it's wise to seek official admission according to the backup story in Adventure Time: Marceline and the Scream Queens #4, which arrives on October 10. Joining regular writer and artist Meredith Gran's main tale, the issue will feature a backup by Yuko Ota and Ananth Panagariya that serves as a cautionary tale against scalping tickets to rock shows in the Candy Kingdom. You can take a look at our first-look at the backup story, "The Bootlegger" -- along with covers by JAB, Zack Sterling, Tally Nourigat and Faith Erin Hicks -- after the cut.From Boom!
