By building up the Power Meter and flying into the Brick Blocks directly above where the player started, the player can reach an oasis, which has a P Switch hidden in one of the blocks. Afterward is a long path with Coins and Coin Blocks hidden as Brick Blocks, followed by some Koopa Paratroopas. At the end of the path are several Coins and Brick Blocks, along with a P Switch hidden in the block above the last. Finally, there are some descending Note Blocks, with the last of which holding a power-up, leading to the goal.
