Yo'ster Isle
Yo'ster Isle is a small island in Super Mario RPG: Legend of the Seven Stars accessible by traveling through Pipe Vault. In the game, it is an optional area and can be easily bypassed by ignoring Pipe Vault and moving on to Moleville. The island is the home to many Yoshies of various colors. Yoshies find entertainment in the Mushroom Derby, a short race on the island's track. The Yo'ster Isle Yoshies enjoy racing and hold events often.
Boshi, a Yoshi with a bad attitude, once was considered the leader of the island because he won every Mushroom Derby race. But with the help of Mario and Yoshi, Boshi was defeated for the first time in a race and the Yoshies began to live freely.
Along with the Yoshies, Raz and Raini, two Toads from the Mushroom Kingdom spent their honeymoon on the island.
