After Kasumi suggests flying at the self-sponsored show, Kokoro Tsurumaki seeks to prove the absurd idea is possible and to make Poppin'Party smile. To do so, Hello, Happy World! invites Poppin'Party to Kokoro's cruise ship, where they put on a concert before going on a hot air balloon, where Kokoro and Michelle jump off the balloon to fly in the sky after some initial mishaps. The show motivates Poppin'Party to do their best in planning their show. (Source: Wikipedia)
