World Bowser-3: Cookie Cogworks

Throughout this level, you encounter rotating cookie cog platforms, some small like the ones pictured here, and others much larger, complete with large “teeth” to stand on. Some move fast enough that you can accidentally slip into a bottomless pit. Pay attention to which direction they are moving!

You can safely fall into the area below the cog with the Spiny Skipsqueaks on it. Avoid the Mega Piranha Plant and collect the Boomerang Flower from the ? Blocks nearby. Try to keep this Power-Up handy for this entire level!

Green Star #1

Using the cog next to another Mega Piranha Plant, you can climb up to a large cog that lets you see the first Green Star suspended in the air next to some Coins. A long jump, or the use of a Cat Power-Up or Boomerang Power-Up, can help you retrieve it.

Next to the Checkpoint Flag is a Sprixie that will help you get a better look at what’s ahead: a large wall covered in massive cogs. The only way up is to use the cogs, and dangerous Piranha Plants infest them.

At the top of that wall, two Mega Piranha Plants will try taking a bite out of you. Don’t get caught unprepared.

Stamp

You pass the Stamp as you take the Clear Pipe away from the twin Mega Piranha Plants. You can use the Boomerang Power-Up to clear away the Horned Ant Troopers, then fall through their passage to get to the Stamp, or you can just leap off the side of the ledge and steer into it.

Green Star #2

The second Green Star is inside a bonus room found in a Mystery Box below another ledge patrolled by two groups of Horned Ant Troopers. You can reach it in the same way you reached the Stamp. The 10 game second challenge in this bonus room is to run along a swiftly rolling platform, avoiding enemies and obstacles until you can reach the star.

Green Star #3

You see the island containing the final Green Star in the distance when you take the Clear Pipe that leads to the Goal Pole. However, there’s no immediately obvious way to reach it.

You want to perform a long jump off the pictured ledge behind the Goal Pole, aiming to land on the island. Once there, ccapture the Rabbit, and the Green Star will appear. You can use a pipe on the island to get back up to the Goal Pole zone.
