Star Marker

Star Markers are types of stars found in Super Mario 64 and its remake, Super Mario 64 DS. These star-shaped shadows mark the spot where a Power Star appears once Mario collects all eight Red Coins in a level. The Power Star appears above the Star Marker once all eight Red Coins have been collected. In Jolly Roger Bay, and in all Bowser levels, there's no Star Marker.
