The Brick Blocks contain Beanstalks and the ? Block on the right contains a Super Leaf. Climbing up the Beanstalk, there are several coin rings spinning around. Even more Beanstalks appear from blocks where there are several Koopa Paratroopas. A Chain Chomp can then be seen on a green mushroom platform. Going past it, there are several hidden blocks containing 1-Up Mushrooms on the right. Going further up is the Checkpoint Flag. More Beanstalks and a Super Leaf can be found. This is followed by circling Paratroopas and a Red Ring. Just after that, several Koopas and a Gold Ring can be found along with more blocks containing Beanstalks. Another Paratroopa ring can be found enclosing the third Star Coin. Further up are more Beanstalks and Chain Chomps. After that, a green pipe leading out of the area can be found. Moving right, a lone red Paratroopa can be seen, followed by the Goal Pole. Completing this level will unlock .
