People who ship the Adventure Time characters Princess Bubblegum and Marceline the vampire queen call the ship Bubbline. We , adventure time fans , ship them since season 2 when Marceline sang “I’m just your problem”. In the last episode (ep. 13, season 10) they kissed and now all the Bubbline shippers can die in peace because BUBBLINE IS CANON
