In Super Mario RPG, players are able to find Yo’ster Isle, an optional area of the game teeming with Yoshis and another minigame.
Though not necessary for completing the game, players are able to find a number of hidden areas within Super Mario RPG. One such area is the Mario-franchise staple, Yoshi’s Island, known in Super Mario RPG as Yo’ster Isle. Players do not have immediate access to the area, and must venture through another optional area in order to reach the tropical region where they can find a bunch of Yoshis and mini-games. Where to Find Yo’ster Isle
Players are able to find Yo’ster Isle any time after clearing the Forest Maze. Once Mario and friends have eradicated the threat to the adjacent Rose Town, players have the option to continue the main quest in the direction of Moleville or make a stop at the curious midway point, the Pipe Vault.
The Pipe Vault is located directly between Rose Town and Moleville and is signified by a red pipe on the overworld map. Visiting the location brings ther player to a small clearing with a single green pipe in the middle, with exits back to the map on either side. Players will need to navigate through the Pipe Vault to reach Yo’ster Island across the sea. How to Get Through the Pipe Vault in Super Mario RPG
The Pipe Vault is a one-block wide area that serves as a nice homage to Mario’s 2D past.
