Once upon a time, there was a big crab with a hard shell. The crab lived near the sea. It liked to play with its friends, the fish and the birds. One day, the crab met a new friend, an amazing turtle. The turtle also had a hard shell.
The crab and the turtle played together all day. They had a lot of fun. The crab said, "I like your shell, it's amazing!" The turtle said, "I like your shell too! We can be best friends." They were very happy.
Then, one day, something bad happened. The crab and the turtle were playing near the sea when a big wave came. The wave carried the turtle far away. The crab tried to snap its claws to help the turtle, but it was too late. The turtle was gone, and the crab was very sad. The crab learned that sometimes, bad things can happen even to the best of friends.
