- Green Star 2: A Fire Flower is needed to get this next Green Star. After riding Plessie, there is an area with two unlit torches. After the player lights them using the fire form, a Cloud Cannon appears and will shoot them to the next area. The player must then run across all of the platforms in order to reveal the Green Star.
- Green Star 3: After the Checkpoint Flag, the player must hop through the Green Star Ring and collect all eight of the Green Star Coins to make the Green Star appear.
The stamp can be found during the area while riding Plessie. It's to the far right near some coins.
