The Wind sighed and said, "But you are one of the fastest-growing plants in the world. You can grow one meter in just 24 hours!" The bamboo replied, "That is not enough. I want to travel far away." One night, a Fairy passed by. She felt sorry for the bamboo. She granted its wish and turned it into a little rabbit. The rabbit was very happy at first. It could hop and run freely. However, it soon got hungry. It tried to eat grass, but it didn't taste as good as bamboo shoots. It missed its life in the forest.
