Artwork of a Green Star

Green Stars are collectibles found in Super Mario 3D World that function in a similar fashion to Star Medals from 3D Land.

In normal stages, there are three Green Stars while in Enemy Blockades, there is only one. The Adventures of Captain Toad stages contain five and Mystery Houses can have up to thirty.

Green Stars are usually either hidden away in a secret area or require a bit of skill to collect. For example, you may need a certain character to get one but then you might need to use a Fire Flower to clear a path to the Green Star.

Certain levels (particularly castle stages) require a certain number of Green Stars to unlock them.
