From Mameruka, "The Land of the Free", hails Nick, the alter-ego of the once-popular yo-yo-wielding superhero Captain Rainbow. He has come to Minmin Island in order to regain his lost popularity. The island is known far and wide as the rumored place where your dreams can come true, and that has attracted a colorful cast of Nintendo's second-and-third tier, long lost and forgotten characters. With the likes of Birdo from Super Mario Bros. 2 USA, Little Mac from Punch-Out!!, Takamaru from Nazo no Murasamejou, Crazy Tracy from Link's Awakening, the soldiers from Famicom Wars, and much more roaming the island, trying to make their dreams come true, Nick has to decide whether to help them out or to use the power of the island and the stars to do what he came here for.
