Now, one obvious objection to this whole idea is that a stage prop would be designed to look hard to get out of, rather than actually being hard to escape, which isn’t necessarily true of these snake restraints. But if there’s some way to release it externally, then messing with that mechanism should still be possible from the inside. Just harder.
And if this person is under some kind of magical control, keeping them from escaping might not be a priority. The mind control ought to be keeping them from doing anything funny, you’ve just found a way to overcome it.
Besides, if these were being designed in a sensible way, they wouldn’t look like headless snakes to begin with. Even if that’s needed to keep Hool from intervening, surely there are easier ways to work in the blasphemy than making the whole thing take a headless snake shape.
Which means it was probably designed shape first, functionality second. And if that’s the case… well, the first thing that comes to mind is actually making them move like real snakes. Might as well try it and see if it gives you any better ideas.
So you start moving the arms of the other actors like snakes, while talking about how they can’t bind you and keep you from charting your own course through life. It’s a cheesy line, but that’s the nature of improv. Sometimes you say really cheesy things because that’s all you can think of.
The thrall follows your motions, and the restraints look like they’re slithering. The thrall looks like they’re trying to stand up, but they keep getting pulled down.
It’s not quite enough, but now you’re thinking in another direction. The restraints are now acting more snakelike. What if you could put heads on them, so they look like real snakes? Would that strengthen Hool’s influence?
The problem with that idea is that stone snakeheads aren’t exactly going to be easy to find. Let alone attach. But then inspiration strikes.
You try to move around and shape your hands so they resemble mouths, then get them around where the empty necks are. This is really awkward, especially as you keep having to adjust when the position doesn’t quite match on the thrall’s side, but after some effort, you get their hands where you want them.
Now you just need a way for the hand-snakes to honor Hool and you might be able to pull this off.
Make the “snakes” look at opposite sides, then say something like: “You don’t all have to go the same way.” Mirroring what you performed earlier
Have them “rest” by lowering them down and staying still. Say something like “You don’t have to hold me anymore”
Have one “eat” the other. Surely Hool will be pleased by this display of power
“You were made to move, not to bind” then guide them to slither away from the body
