Hydroshot

Stephane Lemonnier (from the Blue Planet Mailing List)'s interpretation of a hydroshot spoon.

Hydroshot is Poseidon's most famous original game and primary professional sport. Beginning similar to water polo, hydroshot came into its own by adding a third team and loosening many of the rules about interplayer contact. Each of the three teams tries use a thrower (called a "spoon") to move a ball into either of the opposing teams' goals; success earns the opposing team a point, and the team with the lowest score at the end wins.

Both humans and cetes play.
