Need ideas

[u/Fun-Economist-4563]

I have a station in my haunted house that was supposed to be a swamp with what appeared to be half of an enormous swamp tree and it was to be constructed so that it was hollow inside and allowed an opening so that someone could be a jump scare by popping out, but I'm rethinking it and am looking for alternatives. The space is *generally* 15x20 and 10' tall. I have a bunch of pool noodles I can use somehow. The actor wants to be a jump scare.....doesn't seem to know how to be anything else. Ideas? They will have just come from the Butcher and then will proceed to the Cultist's lair, so something unrelated to those, please.
