On the episode 'class action' characters from Scooby Doo can be found. Right when xj9 says 'great 2.blabla seconds and im allready..' rught when she moves away Velma is standing there. She has small black dot eyes and short brown hair and wears the famous orange sweater. I am not sure but when she gets out of the car with the flip, when it shows the kids for the first time, towards the left closest to jenny, there is shaggy standing there talking. he has short blonde-brown hair. I dont positivley remember but i think he is wearing a green sweater and tan pants.
