Sphere

Spheres (スフィア) are collectible, floating or non-float y items, which by most of the time can be found at Special Stages. There are different colored and numerous variations of Spheres, that in each game gain different purpose for the player, who ever touches them. Spheres have made first appearance in Sonic the Hedgehog 3.

Trivia

 * Originally in Sonic the Hedgehog 3, the Japanese instruction manual stated these items as Ball (ボール). In later games since Knuckles' Chaotix, the Japanese instruction manual have titled them normally as Spheres.
 * Despite being collectible orb-shaped objects, spheres are not to be confused with Gumballs from Bonus Stages in Sonic the Hedgehog 3 and Sonic & Knuckles. As Gumballs earn items, that are inside of them, Spheres only gain boost meter or points.
