Today Giraffe is at the playground. He wants to play on the seesaw, but he can't play on the seesaw by himself. He needs someone else to play with him. He sees Mouse, but she is too light to play on the seesaw with Giraffe. The seesaw doesn't work with Dog and Monkey, either. Is there really no one Giraffe can play with on the seesaw? This happy story teaches the lesson of cooperation, working, and playing together.
