Once upon a time, in a big forest, a little rabbit named Bobo loved to play. One day, Bobo found a big, purple stone. It was rough and shiny. Bobo liked the purple stone so much, he wanted to hide it so no one could take it.
Bobo thought hard about where to hide the purple stone. He saw a big tree with a hole in it. "This is a good place to hide my stone!" Bobo said. So, he put the purple stone in the hole and went to play with his friends.
As Bobo played, he forgot about the purple stone. The next day, it rained a lot. The big tree with the hole filled up with water. When the rain stopped, Bobo remembered his purple stone. He ran to the tree and saw that the hole was full of water. He looked inside and saw the purple stone was now smooth and shiny. The rain had washed away the rough parts. Bobo was so happy to have an even better purple stone now!
