Puffprod Peaks

Puffprod Peaks, or World 2-2, is the second course in World 2, and the eighth level unlocked overall. In addition to completing Conkdor Canyon, 15 Green Stars are needed to unlock this course. It's pretty straightforward.

GS 1: After the stamp, go up the staircase of interactive platforms. The Green Star is above the top left one.

GS 2: There will be a Cannon Cloud in plain sight. Run through a short course with a Super Star for the Green Star.

GS 3: After the cotton puffs with coins in them, go up the staircase, then activate the platform and ride down to the Green Star.

Stamp: To collect the Stamp, which is a Goomba, find the area with the two interactive platforms and two Galoombas. Touch the right one, then go under it for the stamp!
