A long time ago, fish could live either on the ground or in the water. However, what made them live in the water nowadays? Here is the story.

Once upon a time,a cat was hungry. So,it went to the river to find some fish to eat. Suddenly,its father said, “Stop! Don’t you know if you jump into the water, you will die?”

When a fish heard that,it thought that if they lived on the ground, something terrible would happen. So, it visited Doraemon. Doraemon gave a shirt to them. So,it had its adventure.

The fish wore the shirt as fast as it could because it really wanted to leave the water.

Just a few minutes, he saw a lot of fierce animals, such as lions ,tigers and elephants. It thought that living in the water was saver than living on the ground. So, he went back to the water.

The fish said ,“On the ground, there are a lot of animals. Maybe they will eat us.”Then it asked Doraemon to use magic power to make all the fish live in the water only.

From that day on, no fish can go to the ground.
