The deep.

Something was lurking beneath him. A terrible monster capable of swallowing him whole, all he needed to do is keep still and not bleed or he would get eaten by the whale shark  this whale shark was not a normal one it was affected by nuclear rubbish at the bottom of the sea and now it was a true monster instead of having small brush teeth for eating algae it now had giant razor sharp teeth for gobbling up people and had rock hard skin it even had acid drooling out of its mouth, slowly he took out a harpoon and drenched it with poison then he put on a life jacket and got in the water then he shot ZOOM it went right through the water and hit him in the mouth exactly where the whale shark was infected then slowly but surely the whale shark started sinking and sinking and sinking. He had done it slain the monster of the seas, the WHALE SHARK.
