Spinning Heart

A Spinning Heart (also referred to simply as a heart) is a supportive object seen in Super Mario 64 and its remake, Super Mario 64 DS. Spinning Hearts are translucent red hearts that slowly revolve on the ground. When Mario runs through one, the Spinning Heart will quickly replenish his Power Meter in proportion to the speed with which he runs through it. Thus, the faster he runs through it, the more health he recovers. In Super Mario 64 DS, Yoshi, Luigi, and Wario can also use a Spinning Heart to recover health.

Locations
There are 15 total Spinning Hearts across both games, with one in Tick Tock Clock and the one in Goomboss Battle being exclusive to Super Mario 64 and Super Mario 64 DS, respectively. Spinning Hearts are often found in areas with greater risk of damage or before boss battles.

Trivia

 * In Super Mario 64, the Spinning Heart is just a translucent sprite rendered in the 3D scene with collision data. In Super Mario 64 DS, it is an opaque 3D model.
 * In Mario Kart: Double Dash!!, when an item hits the player's Heart barrier, a sound similar to that of the Spinning Heart can be heard.
