Well, as far as I'm concerned, they shall forever be called Serpents.
Well, one of them is a tutorial. It just shows how to get into onestring so that you can pull off instead of them being stuck in onestring.
The other I got right now is just a short clip showing me going in and out of onestring through a link catch. (it makes it to where you can't really see it pop off which I think is nifty.)
