Score by dunking the ball. Don't fall in the water.

This is a very retro fun game. I first saw it being played by @ayrtonbe & @mscccc at the PH office... It's hard to describe, but it's tricky and entertaining,
@jsneedles this looks intense:
We're OBSESSED with this in the PH office on PS4. You get points by throwing a ball into the other players water (and having it sink). You lose points if you drown.
