Star Sphere

A Star Sphere is a clear ball 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 it was a Star Switch, it 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 and protects them.
