Apocalypse Zombie Fish

The experiment done by Dr. Ville has gone terribly wrong. He's left with nothing but pipe-bombs to clean up his mess after the zombies take over. Having bombs the doctor has to save the world. Help this mad scientist cleanse the water. The object is to throw the pipe-bomb close to the zombies. The higher the bomb will fly, the closer it is to the zombie fish. The quantity of the zombie fish determines your account in a round. There are 5 rounds.
