Beep Block Skyway

Beep Block Skyway, or World 4-3, is the third level in World 4, and the twenty-fifth overall. It is a string of platforms that switch in space. It is infested with Double Cherries. It's pretty straightforward.

GS 1: After the first Boomerang Bro., the Green Star is in plain sight.

GS 2: Near the huge slide, go up onto the platform with the blue + Clocks. Go down the Warp Pipe and collect the Blue Coins for the Green Star.

GS 3: After the slide, go onto the P Switches with clones and collect the Green Star.

Stamp: After the Checkpoint Flag, the stamp is above a platform which needs four clones to lift (three Double Cherries). It's a Double Cherry.
