Heave-Hos are red mechanical enemies in Super Mario 64 and Super Mario 64 DS. Heave-Ho's name is a direct reference to the phrase "Heave-ho", which people would say when trying to move something. They appear in Tick Tock Clock and Wet-Dry World. Their faces resemble those of an Amp. Heave-Hos can not be destroyed.
They ride on three wheels, and have a dustpan-like mechanism with footprints on it, which they use to fling Mario upwards. On the Heave-Hos' sides are emblems of Bowser giving a thumbs up, which is over the word "KOOPA" written around in fire. After moving around their area, they lose power, and they have to wind up the key-like object in their backs, much like a toy.
Heave-Hos can help Mario by flinging him upwards depending on the direction they are facing to help him reach higher areas. More often than not, however, they are a hinderance, as the height at which they toss Mario is such that he will take fall damage upon landing (unless he lands on a higher area); this is especially dangerous if he is thrown into a lower level. Heave-Hos cause the greatest problems in Tick Tock Clock, where it is likely that Mario will be thrown into the center abyss and lose a life.
In Super Mario 64 DS, Heave-Hos underwent multiple visual changes, having eyes inside visors instead of a face. The "KOOPA" emblem is gone from their texture. Besides appearing in the aforementioned worlds, they also appear in the Battle Fort stage.
