Decided to post this on a new post, since the Majora post was getting way too long to handle.
The ARG that Jadusable started is back in full swing. There aren't any Moon Children this time around; instead, there's this guy called Ryukaki being forced to run the course. (Youtube | DeviantART (Inactive since '07) | Photobucket (Passworded since 10/8) | Mediafire)
Ryukaki has already posted a handful of videos onto his Youtube account, all of which are directly related to the ARG and are slightly disturbing in nature. Of note, there is sounds.wmv - which is mostly uneventful until two eye-like orbs are seen - and music.wmv - a detailing of the strange phone calls that many users got from posting their phone number on youshouldnthavedonethat.net while it was the Moon Children website.
It's really confusing from here on out, guys... I'd just stay out of it and keep track of things here if I were you.
