Layout
The player starts in an area with a single Buster Beetle, some Brick Blocks, a Hard Block containing a power-up, and a Chain Chomp. If the player has a P-Wing, or is powered-up with a Super Leaf or a Tanooki Suit, he or she can fly to a Warp Pipe leading to a secret area with a chest containing a Music Box, which can be accessed by crouching and flying to a small gap on the right, and another Warp Pipe that leads the player to an area below the main level with four 1-Up Mushrooms. Above there are three Brick Blocks, one of them with a P-Switch, which makes two numbers (three and four) made of coins appear. After that, there are some Nipper Plants, another Buster Beetle and two more Chain Chomps, guarding some ? Blocks, one of them holding a Super Star. Afterwards, there are more Nipper Plants and a Paragoomba, followed by some Brick Blocks and the goal.
