Yoshi is one of the heroes of Mushroom World and an ally of Mario and Luigi. He is a member of the Yoshi race and has aided his brethren in saving their homeland on multiple occasions. Yoshi has also saved other kingdoms from the villain Bowser as well. In his youth, Yoshi managed to rescue and protect Baby Mario and Baby Luigi from the wrath of Kamek and the Koopa Troop. According to Super Mario RPG: Legend of the Seven Stars, Yoshi is the only one of his species who can speak the human language. However, in later games, he doesn't speak the human language (as shown in Mario Superstar Baseball and Mario Super Sluggers). This is contradicted once again, in Super Mario Galaxy 2, when Yoshi speaks in perfect English. Yoshi made his very first appearance, game-wise, in the Super Mario World level, Yoshi's Island 2.
