Adventure Time Science the Rat Sticker
Science is a candy corn lab rat that debuted in the From Bad to Worse episode. This character looks like a piece of candy corn with ears, a small orange nose, feet, and a long yellow tail. Although Finn nearly died by covering himself in the antidote in that episode, Science received the medal because the rat made the antidote. You can see this creature with his earned award in our fanart Adventure Time Science the Rat Sticker.
