Once upon a time, there was a little boy named Tim. Tim had a toy robot with a useful arm. He loved to play with his robot all day long.
One day, Tim wanted to test his robot's arm to see how strong it was. So, he asked the robot to pick up a big ball. The robot tried and tried, but it could not pick up the ball. Tim was sad.
Just then, a tiny ant walked by and saw Tim and the robot. The ant said, "I can help you!" The ant walked up to the ball and, with a big push, the ball moved! Tim was so surprised. The ant was so small, but it was very strong. Tim learned that even small things can be useful and strong. And they all played happily together.
