Our Simmering Lava Lake stars guide details every Green Star in World Castle-7 in our Super Mario 3D World stars walkthrough.

World Castle-7 contains three Green Stars and a single Stamp to collect. If you’re looking for other Green Stars or stamps from World Castle, as well as any Cat Shines from Bowser’s Fury, head on over to these pages:

Green Star #1

Boomerang Flower required! Near the start is a green platform that extends out into the lava. Get to the end, then throw a boomerang to the right to snag the first Green Star.

Green Star #2

Enter the Green Star Ring and collect all eight Green Star Coins while avoiding the Splorches and their lava trails. Collect them all to earn a Green Star.

Green Star #3

Before you enter the clear pipe, head to the right to find a platform that take you to the third Green Star.

Stamp Location

You’ll see this Stamp under a grate where lava constantly enters and exits. As soon as the lava flows away, sprint to the Stamp, then quickly run out.
