Pipeline Lagoon

Pipeline Lagoon, or World 3-5, is the fifth level in World 3, and the seventeenth overall. It is an underwater course. It's pretty straightforward.

GS 1: Before the first Cannon Clear Pipe, climb up into the alcove with a Cat Suit.

GS 2: Shoot a cannonball at the cracked wall, then go into the gold Warp Pipe and collect the coins and the Green Star.

GS 3: After the nine Porcupuffers have been taken care of, go up the indentation.

Stamp: The stamp, which is a Cheep Cheep, is above the area with the Cheep Cheeps and there is an indentation in the wall.
