Crabs live in water which is their natural home. They, like turtles, may come out on land off and on. But they are safe in water only.
One day, a young crab came out of the water and strayed far into a meadow. The meadow was full of green grass and apparently looked a good place to live in.
Little did the crab know that it could be dangerous for him to stay in the meadow for long. So, he stayed on with a view to settling there.
Just then a hungry fox passed that way. Seeing the crab, the fox moved up to it and caught it in his mouth.
Now the young crab realized his folly and said to himself, “I deserve it well ; I left my natural home to be attracted by a place to which I didn’t belong.”
