One day, a gray cat named Sam went for a walk. He saw a big tree and decided to climb it. As he went up, he saw a bird. The bird said, "Hi, I am Tim. What are you doing up here?"
Sam said, "I like to climb trees. It is fun!" As they talked, they saw a screw hanging from a branch. Sam and Tim were surprised. "Who put that there?" asked Tim.
As they looked at the screw, a big wind came. The wind blew the screw off the branch. It fell down and hit a big red button on the ground. The button made a loud noise, and a big door opened. Sam and Tim found a secret room with many toys inside. They played together all day and became best friends.
