Right away this level tosses a curve ball at you: The scenery is constantly scrolling forward, with chain-link fences rising and falling in front of you to block your progress. Collecting everything in the level while dealing with enemies and fences can be a bit of a challenge. The Cat Power-Up, which you can collect close to the level start, is highly recommended.
Green Star #1
The first Green Star requires that you make use of a chain-link fence to retrieve it. The Cat Power-Up is the easiest method, but if that isn’t an option for some reason, stand on the top of the fence to reach it. Alternatively, you can try a wall jump off the fence in the background, but not every character can easily pull that off without Power-Ups.
The two sets of fences here open and close at regular intervals, while two Donut Blocks are the only safe ground between the fences. The Cat Power-Up can dive down the path of Coins to safely get through while the fences are open. Those without it will have to get creative.
Green Star #2
Don’t take the Warp Box right away! Instead, check to the right of the Warp Box and navigate past the two sets of fences to get to the second Green Star sitting on some cloud platforms. The scrolling stops after a certain point, letting you concentrate on getting the star and getting back to the Warp Box safely.
Just past the Checkpoint Flag, the screen starts to auto-scroll vertically. For this next section, the Cat Power-Up is highly recommended!
Stamp
The Stamp is just beyond a pair of Gold Rings at the top of a blue chain-link fence near a Clear Pipe. The Cat Power-Up lets you collect this quickly while putting you in a safe position for the next section.
Green Star #3
Just after collecting the Stamp, if you use the Clear Pipe (or climbed up the fence to get the Stamp), you will find a Cat Wheel. Claw it with the Cat Power-Up to raise a pair of crates into place, which allow you to reach the third Green Star. Now the it’s just a matter of surviving the rest of the way to the Goal Pole!
The action starts scrolling again to the right just after you reach the third Green Star. Don’t get too overeager while navigating the gaps, oncoming fences, and Para-Biddybuds. This is the home stretch before a Warp Box takes you to the Goal Pole area. Try to preserve the Cat Power-Up through this section, as you’ll need it to reach the top of the pole. Look for the Cat Wheel that will raise a platform just enough that you can easily make the jump to the top of the pole.
