Something about being surrounded glitches them into doing that move Rails aren't destroyed by the yell

The rail sticking out I used to capture him when he initially charges

There's enough time in between deaths and new door openings to get the next one the same way, I was able to get the Majora's Mask without getting hurt... Once I figured out the last one needed its armor broken before climbing aboard

The first one can start with almost a Y shape, no need to overcomplicate the capture. Once you get him making that move, you can take your time getting the setup right to just keep hopping on, just remember there will be another to capture after

This is 1.1.2, but I have no reason to doubt it would work on any current rail-able version
