There was a thread on this board from a while back (probably well over a year ago) that had a bunch of videos linked in it. you might go back and check the early threads and see if you can find it.
though I might be confusing it with a thread that linked videos from the pachinko game?
Yeah, that looks familiar, I think that might be the thread I was remembering.
Darn, thanks anyway. If anyone happens to have the videos of these events and sees this post, please post a link!
So I was able to find 虚ろな人魚姫 and 休日乙女 and 憧れのマリアージュ,
so I've found:
and I'm missing:
マミとお茶会inハロウィン (The Halloween event)
If anyone can find these please add a link here.
