The Great Green Shark

There was a problem on the reef- a big green shark was eating everything in its way. So a coral grouper decided to put an end to this. He always teased great white sharks, but the fun ended when the green shark ate them all. He went swimming through the reef, when he saw immense clouds of small fish racing for their lives. Things had always been like this since the great green shark came, crowded and hard to find space for a little exploring.
