Something Fizhy III

Game description:

Score points by swimming a loop of bubbles around the other fish. Your score from each loop is determined by the most common kind of fish in the loop, and increases exponentially with the number of them that you captured. If you catch a fishhook or tin can, you lose points. To get through each level, you need to score a minimum number of points. Don't take too long, or the fish will leave the tank.
