Once upon a time, there was a little boy named Tim. Tim loved to design things with his toy blocks. One day, he made a big tower with his blocks. He was very happy with his tower. But he wanted the tower to light up, like a real building. So he asked his mom for help.
His mom said, "We need a battery to make it light up." Tim was excited. He went to find a battery with his mom. They looked in the kitchen, and they looked in the living room. But they could not find a battery. Tim started to feel angry. He really wanted his tower to light up.
Then, Tim remembered he had a flashlight in his room. He ran to his room and found the flashlight. Inside the flashlight, there was a battery! Tim and his mom put the battery in the tower. The tower lit up, and it was very beautiful. Tim was not angry anymore. He was very happy, and he and his mom played with the tower all day.
