Heave-Ho

Heave-Hos are mechanical windup toys and enemies in Super Mario 64 and its remake, Super Mario 64 DS. They appear in Tick Tock Clock and Wet-Dry World, and in the remake, they are also in the stage Battle Fort. Heave-Hos cannot be destroyed.

Heave-Hos patrol certain areas, using windup keys to move around. Heave-Hos make the sound of a working machine as they move, similar to a Chuckya. After a while, a Heave-Ho loses power, and it winds itself back up to continue moving around. If a player character stands on a Heave-Ho's platform, it flings him high up from behind. The direction that the character is flung in depends on which direction the Heave-Ho is facing. This is sometimes required to reach certain higher areas. This can sometimes result in the character being flung too high, causing him to lose health when he lands. In Tick Tock Clock, this may also result in the character falling down a pit.

In Wet-Dry World, Heave-Hos disappear if the water level rises above the platforms that they are on. If the water is drained to a lower level, the Heave-Hos come back.

In some cases, a Heave-Ho can help the character reach a Star, such as in Tick Tock Clock's mission Get a Hand, where if the character steps on a certain Heave-Ho as it faces a certain direction, it flings the character directly up to the Star.

Physical appearance
Heave-Hos' bodies are a dark red color, and they have yellow windup keys on their backs. They ride on three wheels and have a dustpan-like mechanism with footprints on it. The sides of Heave-Hos have an emblem of Bowser giving a thumbs up, above the word "KOOPA" written around in fire. The word "KOOPA" was left unchanged for international releases. In Super Mario 64 DS, Heave-Hos have undergone multiple visual changes, having eyes inside visors instead of a face and lacking the side decal, and having blue treads instead of the beige wheels from previously.

Trivia

 * The Cataquack, an enemy appearing in Super Mario Sunshine and later games, behaves similarly to a Heave-Ho. Both enemies use flat surfaces protruding from their bodies to launch Mario high into the air.
 * In the Japanese version, getting flung by a Heave-Ho triggers the damage process upon landing even if the fall is not high enough to damage Mario. In international versions, if no damage is taken, Mario makes the same sound effect as if hit by a Koopa Troopa, and he does not flash when he gets back up.
