The shark has been exposed to radiation and is now mutated. He floats in the sea and eats fishes. The more he eats, the more he grows. People are afraid of him and they are trying to destroy him. Try to survive their attacks.
Control the shark with the mouse cursor or by moving your finger on the screen. Fishes swim against you, eat them to grow. Avoid bigger fishes and spiky fishes. Watch out for dangerous barrels, mines, spears and other obstacles. You will pass the level if you grow to the desired size.
