Based on the animated series which follows the exploits of the two young Japanese pop starlets, this Game Boy Advance adventure finds the girls in a bit of a jam -- and not the musical kind. When Ami and Yumi tell Harmony she can't join them on their latest tour, the overzealous fan decides to go on a tour of her own, and she takes most of the band's equipment along with her. Even worse, she also takes Puffy's manager Kaz. Now, through side-scrolling platform challenges and themed mini-games, Ami and Yumi must catch up with Harmony's show, recover their instruments, and rescue Kaz, before Harmony uses Puffy's music and manager to become an even bigger star than they are.Cartridge only.
