World 2-2

Make your way across the curved platforms while defeating the enemies above them. You can activate a gold ring along the way for a chance at some added coins.

Just beyond that, you will spot a Hammer Bro on a brick platform. Defeat it (hit the bricks from below or use a fireball/tail flick), then jump to grab Star Coin #1 above.

Up ahead, you will find a tilting platform that moves based on where you stand on it. Activate the Checkpoint (a save point) after it, and defeat another Hammer Bro along the way.

On the next platform, you will see a vertically-moving ledge. Continue past it and jump to the following platform.

Drop into the gap between the two ledges and enter the yellow pipe below.

Defeat the Boomerang Bros and collect Star Coin #2 in there, as well as many regular coins before exiting.

Jump directly above to reveal hidden blocks, then get back to the upper ledges and proceed onward.

There will be a Boomerang Bro on a ledge just behind a sign pointing upward. At this point, ride the platforms upward while avoiding or defeating the various projectiles being thrown at you along the way.

At the top, go left and jump across to reach Star Coin #3.

From here, simply go to the right of the Sledge Bro and up the ledges to reach the flagpole.
