In a wonderful house, there are many toys, and they all gather together to play every day.

There is a small black ball in it. He is very, very black, like a piece of coal. Other toys thought he was dirty and often laughed at him and said that it was "smoothly ground briquettes."

The black ball is very sad, and at the same time he is envious of the dazzling green toys. There are a lot of toys around them every day, and he has always been alone.
