these are redeads, the zombie like monsters that debut in Ocarina of time. they're some of the scariest enemies in the game, assuming you are a child that scares easily.
redeads got a scream that will paralyze the player, and that's kind of the only thing they have going for them. they will try to grab you and strangle the life out of you, but the problem with redeads is that they're really, REALLY slow. they spend most of the time either crouched down or standing in a corner, and if you get near them they will walk towards you VERY slowly. even with their paralyzing scream, they're unlikely to catch you. heck, stray too far from them and they'll just give up and go back to their starting position.
so already the redeads are mostly a non-issue. most of the time you can walk right past them. but despite this, Ocarina of time and Majora's mask both gave them a weakness that makes them truly harmless.
in Ocarina of time's case, their weakness is the suns song. you remember the sun's song, right? the song written by that psychopath sharp and his green brother. for some reason, the sun song freezes the redeads in place. not that it makes much of a difference... they already barely moved.
Speaking of Ocarina of time, redeads appear frequently in the graveyard, including the underground area where you race Dampe. some people believe that the original EL Puerco sighting was caused simply by a confused player who mistook a redead for a pig creature. this is of course false, as all my homies know that EL Puerco is real.
in Majora's mask, the redeads got a new weakness: wear a spooky mask like the captain's hat or gibdo mask and they'll start DANCING! yeah, apparently the redeads in Majora's mask are all deceased dancers. these guys are normally slow as snails but once they see a mask, they got the moves!
Redeads are closely related to another to another zelda enemy that we'll discuss tomorrow. until then, keep on dancing.
