Once upon a time, there was a green frog named Fred. Fred loved to wear a big green hat on his head. He thought it made him look very cool. Every day, he would hop around the pond and show off his hat to all his friends.
One day, a little fish named Tim saw Fred's green hat and wanted one too. But Fred was selfish and did not want to share his hat. He told Tim, "No, you cannot have my hat! It is mine!" This made Tim very sad, and he swam away with a frown.
Later, Fred saw Tim crying and felt bad for being selfish. He decided to share his hat with Tim. They took turns wearing the green hat and soon became best friends. They learned that sharing was much more fun than being selfish, and they played happily ever after.
