Instructions
Locate a Yoshi egg and bring it the fruit that it desires to hatch it. Mount the Yoshi.
Determine the color that you want the Yoshi to be: purple Yoshis make platforms that move horizontally, pink Yoshis make vertically-moving platforms and orange Yoshis make stationary ones.
Locate and have your Yoshi eat a pineapple or lemon to turn your Yoshi orange. Locate durians or red peppers and make your Yoshi eat them to turn your Yoshi purple. Have your Yoshi eat bananas and coconuts so that his color changes to pink.
