Influenza tontonbū-gata

The influenza tontonbū-gata (インフルエンザトントンブー型, pig-type influenza) is a mysterious illness that appears in the last chapter of Super Mario-kun volume 7.

While preparing a party for Mario and Luigi, the Mura Mura citizens fall ill of the influenza tontonbū-gata, and they all turn into pigs. Once Mario, Luigi, and Yoshi arrive, even Luigi gets infected and is turned into a pig as well. The Mura Mura chief explains that a cure exists in the form of the Star Hana. Mario and Yoshi find the Star Hana on top of a Chō Dossun, and Mario defeats him by injecting him with the same flu, turning the enemy into a pig and taking the flower from his head without any problems. Later, Mario cures Luigi and the Mura Mura citizens.
