 The default Yoshi is green, but the game also has hidden blue, yellow, and red Yoshis; the player can obtain each coloured Yoshi by finding its egg in hidden areas and feeding it five enemies or one star, causing the baby Yoshi to mature.Although the main objective is to navigate through seven worlds to reach the end of the game, the player can beat the game much faster by using secret Star Road routes.To access a hidden world, the player needs to find key scattered throughout the game's levels.
