Part 28

From the start, move south-west away from the Giant Boo. Platforms will appear as you reach their edges. Continue moving south-west and south-east across these platforms until you reach yellow platforms.

Face the Giant Boo to make him stop chasing you. Move quickly across the yellow platforms.

Stop on the second yellow platform. Wait for all yellow platforms to move back together. Then, move to the next platform and jump to the ground on the other side.

Go to the far right of the room and break the brick blocks. The right one has a coin, the left has a Super Star.

If the Giant Boo is not reachable, turn away until he is. Run through him while invincible to defeat him.

Continue through the purple door.

Jump to grab a coin, which forms a platform. Jump right to the next platform, then right again to the top one. Run and jump off the right edge to reach the top of the Goal Pole.

World 4-5: Move up to the next platform and step on the green ! Button. Follow the appearing trail to the next ! Button and step on it.

Follow the coin trail that appears after stepping on the first ! Button. This will activate all four ! Buttons.

At the end of the coin trail, climb steps to the next platform. A Boomerang Bro will appear. Stomp him while avoiding his boomerangs. You can also stomp the boomerangs.

After defeating the Boomerang Bro, hit the Mystery Box between the two brick blocks. Collect coins from invisible ? Blocks in the 10-second bonus area.

Hit the right brick block for a coin.

Star Coin Alert! #1: Hit the left of the two ! Buttons, then immediately run and hit the right one. Follow the path that forms until it doubles back. Jump to a higher small platform on the right side to grab the Star Coin. Continue following the path, collecting coins, to reach the platform above.

Hit the left brick block for a coin, then hit the Warp Box.

After warping, move north-east and hit the Checkpoint Flag. Continue north-east and step on the ! Button. Follow the trail.

Deal with the Stingby, then jump onto the yellow platform. Jump from the yellow platform to the next ! Button and follow its path. Jump over spiked blocks.

Ground pound the right-most brick block on the temporary path and deal with the Stingby.

Hit the left block of the right couple of brick blocks for a Tanooki Leaf, and the others for coins. Jump onto the yellow platform before it moves away.

Star Coin Alert! #2: Use the Tanooki Leaf. When the yellow platform reaches the Warp Box, jump over it and hover. Wait for the yellow platform to appear on the other side of the Warp Box before landing. It will move until it's under the Star Coin. Jump up to grab it. Hit the Warp Box.

You will warp to an area with ! Buttons and a Boomerang Bro. Defeat him.

Step on the three ! Buttons on your right. Jump onto the platform they create and grab the five Blue Clocks.

Star Coin Alert! #3: (Details for Star Coin 3 are not fully provided in the source text, but it is indicated to be in this area after activating the ! Buttons and collecting the Blue Clocks.)
