Players, please keep a safe distance from the surface of the water. We don't want any... accidents.
No diving for treasure, no fishing for treasure, no treasure hunting for treasure. We're here to play hockey, people! (But if you do find treasure, don't forget to share.)
Don't bother the local sea life. They're trying to live their best lives, just like you. Treat them with the respect you would want for yourself. (Or, you know, just don't touch them, and they'll be fine.)
