Zootopia - Ending Explained

The Twist: The kind, mistreated Assistant Mayor Bellwether is the mastermind. She has been synthesizing 'Night Howlers' (a toxic flower) into a serum and having it shot into predators to make them go savage.

The Plan: Her goal was to incite a race war, using the fear of the 10% predator population to unite the 90% prey population under her rule.

The Ending: Judy and Nick stage a fake 'savage' attack to trick Bellwether into confessing while recorded on the carrot pen. Bellwether is arrested, the savage animals are cured with an antidote, and Nick joins the ZPD, becoming Judy's partner.

The Crack Cocaine Allegory: Some critics view the 'Night Howler' plot as an allegory for the CIA/Crack Cocaine epidemic of the 1980s, where drugs were allegedly introduced to minority communities to destabilize them and justify heavy policing.

The Flawed Biological Metaphor: A common critique is that the predator/prey allegory breaks down because in the film, predators were historically dangerous, whereas real-world minorities have no biological predisposition to violence. This leads to an interpretation where the film unintentionally validates the fear of the minority, even while trying to debunk it.

Queer Coding: Nick Wilde's story of hiding his true self and finding community in the 'underground' is often read as a queer narrative, with the muzzle representing the closet or societal suppression of sexuality.
