One day, a big fish named Bob lived in the sea. Bob was a shark. He liked to swim fast and rush through the water. He had many friends, like little fish and big fish. They all played together in the sea.
One day, Bob saw a big thing in the water. It looked like a fish, but it did not move. Bob was scared. He thought the big thing was a dead fish. He told his friends about the big thing.
But then, something unexpected happened. The big thing started to move! It was not a dead fish. It was a big boat! The big boat was nice and did not hurt the fish. Bob and his friends were happy. They played around the big boat and had fun.
