Platform-raising Wheel

Spinning Wheels are obstacles which make appearance in Sonic the Hedgehog 3 and can be found at Marble Garden Zone.

Description
In order to use blue and yellow colored obstacles, the player must perform the Spin Dash whilst making contact with the object. Doing so causes doors to unlock or platforms to rise from the ground, allowing the player to progress further.

Spinning wheels make reappearance at Sylvania Castle Zone of Sonic the Hedgehog 4: Episode II, serving the same function as objects did in Sonic the Hedgehog 3. In the game, spinning wheels mostly open the rock doors.

Trivia

 * In Sonic 3, should the player jump on top of this obstacle and then spin dash on it, the character will be thrown backwards into the air, still in spin dash position.
