One day, a smart cat and a little dog were playing in the park. The cat had a big red ball. The dog had a small blue ball. They were very happy.
The smart cat said, "Let's hide our balls under the tree and go play tag." The little dog agreed. They put their balls under the tree and ran to play tag.
After playing tag, they went back to the tree. But, they could not find their balls. The smart cat said, "I have an idea. Let's look under the other trees." They looked under all the trees and found their balls. The little dog said, "You are so smart!" They played with their balls and had a fun day.
