So yeah, I was watching a youtube video of a mouse falling into a Nepenthes pitcher plant, and one of the comments was that the pitcher plant worked like the Sarlacc from "Star Wars"
I did some research on the Sarlacc and thought "OMG, this is horrible!"
Basically, the Sarlacc swallows you alive, and when you fall into the digestive chamber, these things come out of the stomach and hold you against the wall. They dig into your flesh and inject you with liquids to keep you alive for thousands of years as you are slowly digested.
Holy crap, who thought of this?!?
