I'm not for sure if this is what you are looking for, but it may give someone an idea!
I had an "under the sea" room for the past 3 years. For the past two years, each child had a ship or a boat with their name on it. If a child misbehaved or broke a rule, he or she had to move their boat. Here were the infractions:
One "move" - "Rough Waters" (this was their warning)
Two "moves" - "Stormy Weather" (missed half of break)
Three "moves" - "Shipwrecked" (missed all of break, note sent home)
