Shaggy grabs a slice of bread and puts it on the top of a 6 layer sandwich. He goes to eat it until Scooby steals it with his tongue. The three turn to a waiter with a plate covered. Scooby takes off the plate cover and sees a werewolf head. The three then look up and see that the head had belonged to the waiter. This alone sends the three running
