Floormaster

The Floormaster is a close relative of the Wallmaster. In fact, the two species are often identical or near-identical in appearance. Unlike Wallmasters, who hide on the ceiling or walls, Floormasters will remain on the ground but are just as ruthless and terrifying as their counterparts.

Ocarina of Time and Majora's Mask
In Ocarina of Time and Majora's Mask, Floormasters take on the appearance of giant severed hands. When they're about to attack, they glow green, hover, and clench their fists. When you attack one, it will split into three smaller hands. These tiny Floormasters should not be taken lightly however. Upon splitting, the creatures will retreat, but after a few moments, they will turn to attack. If a tiny Floormaster grabs Link's neck, others are certain to follow, so take them out quickly. If allowed to live, tiny Floormasters will merge into one larger hand again. In Ocarina of Time, Din's Fire is a great weapon for getting rid of tiny Floormasters, if used immediately after slashing a Floormaster, to prevent the tiny ones from getting out of range. In Majora's Mask due to their nature as creatures of darkness, Floormasters can be quickly dispatched by concentrated light, such as that directed by the Mirror Shield or carried by Light Arrows.

Occasionally, Floormasters may be invisible. Use the Lens of Truth to see them.

Oracle of Ages and Seasons
Floormasters appears in both Oracle of Ages and Oracle of Seasons and they take on a slightly different role. Floormasters are not visible immediately but they will appear from underneath the floor to try and grab Link. The Oracle series also has Wallmasters, but the Floormasters are distinct because of their blue color.

The Wind Waker
The Wind Waker's Floormasters are radically different from their previous incarnations. They look like giant, thin, dark hands surrounded by a purple glow, sticking out of a dark vortex, and bear an uncanny resemblance to Majora's Mask's Dexihand or ???. Their behavior is much more akin to that of Wallmasters then that of Ocarina of Time's Floormasters: They will try to grab Link, and when they do, they will take him back to the beginning of a dungeon. They can be killed with a few slices of the sword or with just about any other weapon. They're quite difficult to dispatch since they only emerge from their holes when Link comes close enough to be grabbed. Despite their lack of any visible mouths, they often utter a strange whistling noise and screech loudly when injured. If there are any objects (chairs, skulls, pots, etc.) lying around nearby, Floormasters will not hesitate to pick them up and throw them.

Interestingly, The Wind Waker's Floormasters are the only ones in the series that do not take Link back to the beginning of the dungeon but rather just a few rooms back or to the beginning of the room.

The Minish Cap
The Floor Masters attack in groups of two most of the time, and sometimes will block the way through to a tunnel.

Four Swords Adventures
Floormasters only appear in the level "The Lost Woods." They will rise up out of the forest floor and grab at Link. If they succeed, Link will be pulled to the Dark World, where he must find a portal out. This incarnation won't harm Link and cannot be harmed themselves or killed; but a swipe of the sword will stun them for a second or two. They mostly attack in swarms.
