- Green Star 1: The first green star is not hard to spot, as it is floating over a pool of lava. To retrieve it, you must use a boomerang flower.
- Green Star 2: To collect the second star, touch the star-shaped coin ring and, in the few seconds with which you are provided, collect all eight coins.
- Green Star 3: A little while after the stamp, you will see a platform sinking and reemerging from the lava. When it is above the lava, hop on it to get the last star.
After the checkpoint, there is a platform rising and falling into the lava. This is where the stamp is. Wait for the lava to lower and snatch the stamp.
