The last Moon Coin is under a group of donut lifts. The next Moon Coin is right after the checkpoint, but as it’s in a pit, you’ll need a Koopa shell to collect it for you – the Koopa to your right should work nicely. Just be careful of the platforms’ movements as you jump to collect this Moon Coin. If you revealed a P-Switch in the blocks to the left, it’s safe to press it as it turns the brick blocks enclosing the Moon Coin into coins. Don’t hit the switch until you’ve collected the Moon Coin. Just before the flagpole, you’ll see a Moon Coin and a ? Switch. To get it, you’ll need a Koopa’s shell, which you can toss from the second windmill (a bit risky) or you can make a path to the right of the Moon Coin through ground pounds, and toss the shell that way. The Moon Coin is to the lower right of the second block windmill after the checkpoint.

drop down, wait for the P-Switch chime to finish, then go in the pipe, which will launch you into the Moon Coin. Hit the block to the right and step on the P-Switch. You’ll see this Moon Coin after the first windmill of blocks.

To access World Star, clear World 6 and have 90 Star Coins (you should have them, seeing as you’ve been following this guide =P) – you will need to spend the Star Coins to access Star-1. Note that the Coins that you collect in this World are called “Moon Coins” and have the moon icon from Super Mario World on them.
