Dexihands (デキシーハンド, Dekishiihando) are turquoise arms with yellow finger tips from Majora's Mask, slightly similar to Floormasters in appearance. These can be killed by Zora Link's boomerang fins or electrical shield. If Link gets too close, these monsters will grab his body, then fling him around for a few seconds before throwing him away. Dexihands often guard treasure or something needed to progress in the game. While a normal Dexihand will always toss him in the same direction he approached it from, specific ones will throw him away from what they're guarding.

In The Wind Waker, there is a similar enemy called the Dexivine. This enemy drains magic power from Link when he gets within reach of the claw-like vine. "Dexivine" is a fan-based name, it's real name is currently unknown.
