Green Stars (Super Mario 3D World)

- Green Star 2: In the second clear pipe loop, there is a Green Star.
- Green Star 3: Be in Fire Form to break through two Spike Balls to reveal a pipe leading to a Lakitu Cloud leading to a different area. Make it to the end of the area to get the star.
Stamp (Super Mario 3D World)
After the checkpoint, there is a long clear pipe. Rather than launching yourself through the pipe, jump on top of it. You may need a cat suit, seeing as the pipe curves upward, but if you want to you could also try to jump up. If you succeed, the stamp will be right there.
