Good Idea/Bad Idea

[Crumplehat]

A Star Wars style disposal system that empties into a sewage tank would be pretty hilarious

Branching off of that, maybe a crusher that's actually a crusher? Like, a little pit with walls that gradually close inward at regular intervals to destroy what's in the pit. Like an Indiana Jones trap or something. Make it so if you fall in you have enough time to maybe escape but if you're too slow, it's squish.

Additionally, on the Star Wars angle, maybe put a cyclopean pit monster in there that sometimes attacks people who fall in.
