I think it's a glitch, but you can do fun things with Kargarocs in Wind Waker if you freeze them.
Spin spin spin.They push you when they spin.They stay in the "hurt" position sometimes...Easier to see.Yeah. Interesting. I got them to spin through the rock once, but I didn't have my camera ready. I haven't been able to replicate it, either. In the third video, if you look closely, it's still flying around, but it's still in its "hurt" position. Near the end, you can see it go back to normal once it spots me. The fourth video is just brighter and closer up, but doesn't show it go back to normal. It also seems that, in order to keep it in the injured position, part of its body has to be inside of a solid object (like the rock I was on) when it unfreezes.
It's also probably worth mentioning that they never seem to die when you're shooting them with ice arrows, but they'll die in one hit from normal arrows. How silly of them. :(
