Power Star

Power Stars are the main collectible of Super Mario 64. They are a reoccuring item in several other Mario games, either being a power-up making Mario invincible, or a collectible. They are obtained by finding them throughout the courses and castle, usually through the star select screen, where you select scenarios AKA missions, with specific situations to obtain a star. When a star is collected and seen again, it will be translucent and a shade of blue.
