Star Sphere

A Star Sphere is a transparent bubble that holds Stars.

In Super Mario 64 DS, if a player receives five Silver Stars or presses a Star Switch, then a Power Star will appear in the ball. If a Star Switch is pressed, the Star Sphere will only last for 10 seconds. When the Star Sphere is touched, it will break, allowing the player to get access to a regular Power Star or a Secret Star.

The Star Sphere reappears in Super Mario Galaxy and Super Mario Galaxy 2. In these games, the Star Sphere holds Silver Stars.
