If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
The piggy and the penguin are now ready for a rescue mission. Just catch the fishes to drop them into the sea in order to save them. In the first two levels, the boat will have to avoid the bombs to rescue fishes. If the boat is hit by the bomb, you lose a life. From the third to the fifth level, the boat will have to avoid obstacles like rock, tree and the bomb. The fifth level also has a dolphin. Go high and rescue as much fishes as you can after which you can move on to the subsequent levels.
Click the mouse to make their motor boat go higher. When the loader gets full, the boat will have to be lowered to make it climb again.
