Swim deep in the ocean as a scuba diver gathering rare and precious seaweed. Use your mouse to control the swimmer and collect as much seaweed as you can, but try not to pick up the blue poison seaweed! Crabs, fish and sharks all impede your efforts by damaging and trying to eat you. Poison seaweed will subtract points from your score - by twice as much as good seaweed adds to it! Advance through the levels by staying alive long enough to get the required amount of points. Powerups and bonuses make your job a little easier, but don't depend on them!
