Enter Tall, Tall Mountain as Yoshi and get a cap. Get to the top of the stage and throw the monkey off. Then, go to the monkey that steals your cap. Pick him up and lose your cap. This is the tricky part - jump and eat the cap off of his head. If you eat the monkey, try again. If you ate it off of the top of his head, your game will freeze!
