Our Koopa Troopa Cave stars guide details every Green Star in World 1-2 in our Super Mario 3D World stars walkthrough.

World 1-2 contains three Green Stars and a single Stamp to collect. If you’re looking for other Green Stars or  stamps from World 1, as well as any Cat Shines from Bowser’s Fury, head on over to these pages:

Green Star #1

When you reach the cloud platforms, jump onto one of the lower platforms on the right, then jump and grab the first Green Star in the middle.

Green Star #2

After you pass the fire torch, jump up the purple brick blocks and enter the Warp Block. Defeat the two Koopa Troopas in this room to reveal the second Green Star.

Green Star #3

Towards the end of the level is a Goomba Towers with the last Green Star in the middle. You can either jump from the higher platform to to take them all out, or you can throw a Koopa Shell to slowly take them out one by one.

Stamp Location

As you pass through one on the clear pipes, you’ll notice the Stamp in a hidden area above. Return back through the pipe to the area with the single long block. Hop on top and jump to reveal another hidden block. Do this again until you can reach the top of the ledge. Enter the clear pipe on the wall to have it take you to the room with the Stamp.
