This is a lot of fun. You are a piranha and the thing you love to hate most in the world is pirates. You hate them but they make the best little meal and you derive immense pleasure from reducing them to nothing but bone. Flip their bones and feed until they are nothing. Collect bubbles of blood to upgrade yourself. Complete the tasks you are given in each level. They will be increasingly harder. An easier task might be flipping a boat and eating all of the pirates and a harder one would be getting the pirates off land. When out of water pay attention to the breath bar above you in blue.
