you are dustins pet, but you aren't any ordinary pet. you are connected to the Demogorgon; you roar the same, have the same body parts. dustin knows you are a secret, but your demogorgon face hasn't open yet. he keeps you in a tank but you escape a lot. one day he rushes into the room. "sorry dart, the party is coming today. you gotta stay quiet. sorry if its a lil' dark."
