Mike had always enjoyed hula hooping, but he was constantly made fun of by his sister. She teased him that it was a girlie activity, and she warned him not to do it at school unless he wanted to be bullied. So he kept his hooping love a secret. That is until a strange incident at school where Mike's entire class found they had swapped bodies with each other. For a short while, Mike felt devastated because he switched bodies with Joy, an exchange student from Taiwan. But after he thought about, he realized it might not be so bad. His sister's warning about hula hooping at school no longer applied. He could do it any time he wanted! In fact, his hula hooping soon made him one of the most popular girls in school. Is it any wonder why?
