I'm Game #21 (Katie Kazoo, Switcheroo)

The "Katie Kazoo" series is about an elementary age girl who received a granting of her wish to be someone else. In each book in this series she experiences (temporarily) a change into someone else, and during the period of change she usually creates a conflict that she has to work to resolve after she turns into Katie again. My daughters (similar in age to Katie) love these books and usually consume them in a single day (or a single sitting). The conflict is low-grade and typically funny or light-hearted. "I'm Game" is about Katie turning into her own Dad right before he appears on a game show. He ends up looking silly because she can't fake it entirely. One of our favorites in the series.
