Kero Kero Keroppi no Yowamushi-ouji no Daibouken

Keroppi is blamed for the tomfoolery of others during a movie. As he runs home crying he is struck by lightening and transported to another world--just like in the movie! There he meets a cowardly prince and the both of them go on adventure to learn about courage and sticking up for oneself.
