So I've seen a few things this year but not everything.
Killer Klowns had two rooms with 3 red buttons. I could be mistaken but I think one makes a noise when pressed while the next room one of the buttons sprays water.
In Universal Monsters, there were some ropes and most didn't have much give but there was at least one that did have some slack to it. I wasn't sure if this was similar to 2016's Tomb of the Ancients or if it was just a loose rope. I am always afraid I'll break something.
In House of 1000 Corpses, there is a bell on Captain Spaulding's counter that does ding. Surefire way to get an icy glare from the scare actor.
I haven't seen the Jack bag yet. What else am I missing?
