World 6-1: Clear Pipe Cruise

At the start, take the first clear pipe to an island with a Fire Piranha Plant. Defeat it, then move to the next clear pipe where another Fire Piranha Plant awaits. Defeating the second one yields a Fire Flower.

The pipe to the right leads to an invisible cloud platform. Shoot fireballs to destroy mines and collect hidden coins.

Green Star #1 is ahead, blocked by mines. Grab the Super Star from within a pipe, then head left to collect the Green Star before invincibility wears off.

Use the Warp Box to the right to reach the next area. Hit the POW Block to get a power-up from the ?-Block above it.

Shoot a fireball through the clear pipe to the left to defeat a Piranha Plant across the gap, then follow through the pipe.

Destroy the mines inside the bottom pipe with the Fire Flower to get an easy 1-Up Mushroom.

In the next area, Fuzzies move through clear pipes. Time your movements to enter and exit safely. The first pipe has a clock pick-up, the second has Green Star #2. Cycle around the top section until Fuzzies pass, then re-enter the main pipe to exit.

Hit the Checkpoint Flag. Instead of using the Clear Pipe Cannon, climb atop it. When the pipe turns skyward, use a Cat Suit to reach the top and place the Stamp. Alternatively, wall jump off the pipe, turn upward, and perform a mid-air roll.

In the next area, use a Cat Suit to race up the wall or use Clear Pipes to avoid Fuzzies. Get a power-up from the ?-Block on the second level with clouds.

Take the Warp Box. At the top, shoot a Fireball into the clear pipe to your left, then follow it to a Cloud Cannon.

This leads to a bonus cloud area. Instead of a Super Star, grab a Piranha Plant at the beginning. Claim Green Star #3 at the end of the run.

Head down the ramp, defeating Piranha Plants.

The final area requires five Key Coins to use the Warp Box. Key Coin #1 is at the entrance to the Clear Pipes.

Dash right, dodging Fuzzies, to grab Key Coin #2 and Key Coin #3 from the top right.

Go up or down to reach the left side, depending on Fuzzy movement. Get Key Coin #4 and Key Coin #5 from the symmetrical left side.

Enter the Warp Box. Move through the clear pipes, exiting at the top to reach the Goal Pole.
