Bringing a Cat Power-Up to this level is pretty handy in case you slip up, which is easy. Ride over to the theater walls and use the tilting platform to hit the trapeze, making a swing to the next ledge. From here jump to another trapeze over to a tilting platform. With the Cat Power-Up, climb the wall up to the cloudy platform and claim Green Star #1 .
If you don’t have one, you’ll need to use the next trapeze to launch yourself to this position. Swing over to the next gondola that takes you to the Checkpoint Flag . The rotating platform ahead has plenty of Piranha Plants but the ? Block in the center holds a Mega Mushroom , the perfect item for clearing the entire platform. Once you’ve cleared it, head right across some Donut Blocks to a pipe. Hit the P Switch to spawn Blue Coins that need to collected within the time limit. If you make it then you’ll receive Green Star #2 and can return to the rotating platform.
Use the Mushroom Trampoline to bounce up, then turn left to spot the Stamp for an easy collectible. Ahead is a series of trapezes that you’ll need to be quick with since the Green Star Ring will be triggered here and all the coins will require precision and speed to collect Green Star #3.
The end is easy to cap with the Cat Power-Up or Tanooki Suit, so use one of them to receive your golden flag for topping the Goal Pole.
