Judy finds out the missing animals, still "savage", are being held captive. The Mayor is responsible for their captivity in order to prevent panic, but doesn't know what's causing it, and resists efforts from others to come clean to the public. Judy calls her colleagues who arrive and arrest the mayor. At a press conference she admits that only predators seem to be affected, and without thinking, suggests that they might be reverting to an unevolved state. Nick, a fox whom she befriended while helping her solve the case, is understandably offended by this, and essentially accuses her of being prejudiced. Dejected, she quits the force and returns home to be a farmer.
While back on the farm, she is apologised to by her childhood bully, another fox, and hears about plants called "nighthowlers" which can cause animals to turn savage. She remembers the weasel she arrested on her first day was stealing them, but didn't realise their effect at the time, and that they're being used to attack animals back in Zootropolis. She races back and with Nick's help tracks down the weasel, who leads her to an underground farm in an old subway carriage. Escaping with the evidence, they call for help.
The carriage is destroyed but they manage to save a gun with the concentrated toxin. The assistant mayor, now mayor, arrives and wants to take the evidence, but suspicious of how she got to them so quickly, Judy resists, eventually realising she was behind the plot from the beginning, wanting to divide the citizens of Zootropolis and keep them in fear of predators. The mayor shoots Nick with the toxin in order to turn him savage so he'll kill Judy, and appears to, before revealing he switched the toxic pellet with a blueberry, and they were just stalling for time so the cops could arrive - they do, and the mayor is arrested. Peace is restored, divisions are healed, and Nick becomes the first fox recruit to the ZPD.
Continuity mistake: During Judy's chase, Duke Weaselton falls beside the large donut sign and the bag filled with flower bulbs lands on the street near the sign, but in the shot of Judy running down the street yelling, "Stop right there" the bag has moved much further up the road beside double yellow road lines. Then, after Weaselton kicks the donut and it rolls down the street, the bag has vanished from both areas, though the bag reappears after Judy saves Fru Fru.
Nick Wilde: It's called a hustle, sweetheart.
Trivia: The Zootopia taxicab service is called Thigmo Taxis, which is a pun adapted from the biological term "thigmotaxis," meaning "Movement of an organism toward or away from any object that provides a mechanical stimulus."
Question: When Judy starts her mission to find Mr. Otterton and finds Nick with his partner, Finnick, she manages to hustle the fox, get him to confess his crimes on a voice recorder, and forces him to assist her on her mission before she decides to arrest him. Finnick laughs at Nick's humiliation and walks away. Why does Judy let Finnick off the hook despite the fact he was involved in Nick's scams?
Chosen answer: Finnick didn't say anything that could be used against him and she had no proof that he was delinquent on his taxes, as he said, "She hustled you good!"
Finnick was involved in all of Nick's scams so shouldn't he have been charged as an accessory and therefore also forced to help Judy?
Nick's crime was not paying taxes. Judy had no evidence that Finnick was guilty in any tax evasion or that he even participated in earlier scams.
Judy witnessed Nick and Finnick involved in a scam involving popsicle sticks that he and Finnick used to create pawpsicles and sell them to lemmings. They also sold the popsicle sticks to mice for construction. The scam involved melting down a Jumbo-pop to make smaller pawpsicles and then reselling them.
Which, as Nick explained, was perfectly legal. Also, Judy had no desire to arrest Nick, only to force him to help her. His partner was of no use to her, so she let him go.
