How the heck do you get this piece? I've seen it before and I assumed you could get it by riding the turtle into it, but I'd never actually tried before. As I found out here, riding the turtle doesn't take you to that piece. Doesn't seem like I can just let the current carry me into that piece, either. Hrm...
Oh wait, this piece is in the oasis jail area... oh! That means I have to catch the underwater turtle right now! ...Dang, he's just entered the tunnel, I was a couple seconds late.
Fortunately, I practiced going out of bounds and flying to the oasis jail area to bypass the turtle's tunnel. This is a little better than waiting another minute for the turtle to come back. My execution wasn't great, but it shows the general idea.
I think I fell through the floor? I'm not sure. If so, maybe it was because I jumped off the pulley while it was at its lowest point, placing me under the floor somehow. I dunno. In any case, I guess there's no reason to try and jump onto the pulley (as opposed to walking into it), so I won't be doing that anymore. >_>
