Plot
The original plot featured Nick having an idea to create an amusement park called "Wild Time" — a place where predators could be free and have fun. There was going to be a scene where Judy and Nick stumble upon a "taming party," where a polar bear cub is being fitted for his first collar.
Basically in this version, predators have to wear shock collars(called "Tame Collars") cause prey see them as vicious, bloodthirsty monsters.
This version I would've actually wanted to see, to get a break from "Constant Sunshine and Rainbows" that is usually Disney movies. This verion of the movie was MUCH darker.
In this version, the tame collars are they prey's way of saying "Instead of living in harmony, we can make predators equal by controlling them".
