Mura Mura (ムラ村, Irregular Village) is a village located in Yoshi's Island that only appears in Super Mario-kun. Its name is a wordplay on the word "mura" which, depending on the writing, means both "uneven" or "irregular" and "village".
As a way to thank Mario and Luigi for saving Dinosaur Land from Bowser, Yoshi has organized with his people a party with "cute girls" at Mura Mura. However, when the three reach the village, they find it inhabited by pigs: a mysterious illness known as the influenza tontonbū-gata has spread and turned the Yoshis and Luigi into pigs. Mario is informed by the village chief that a cure to this illness exists in the form of the Star Hana. Mario and Yoshi find the rare flower and return to the village to cure everyone. Much to Mario's disappointment, he realizes that the "cute girls" Yoshi told him about are just female Yoshis.
