So, why wouldn't it apply now as well? Well, while so far you have the chance to play with spaceships, worms, play sports, with dots and other things, this time you go to the sea, where you will become a pirahna, a pirahna ready to eat all the others, and become the biggest one. How will you do that? We will explain right now, so keep reading! Using the mouse you will control your predatory fish, eating the different children in the water, in order to get bigger and bigger. Other players will do the same, and big fish can eat small fish, so make sure that doesn't happen to you.
