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 Star Sphere. If a Star Switch is pressed, the Star Sphere will only last for a certain amount if time. When the Star Sphere is touched, it will break and the player will get the Power Star.

The Star Sphere reappears in Super Mario Galaxy and Super Mario Galaxy 2. In these games, the Star Sphere holds Silver Stars. It is notably like a bubble, as opposed to a crystal.
