Once upon a time, there was a gray bird. The bird liked to fly high in the sky. One day, the bird saw a big tree. The tree had many leaves, but it looked sad.
The bird asked the tree, "Why are you sad?" The tree said, "I want to become a big, strong tree, but I am too small and gray." The bird wanted to help the tree, so it flew away to find help.
The bird found a magic seed. The bird took the seed to the tree. The tree ate the seed. Something unexpected happened! The tree became big and strong, but it also turned into ash. The bird was sad, but it knew the tree was happy now.
