Zootopia 2

One week after Judy Hopps and Nick Wilde become partners in the Zootopia Police Department (ZPD), their clashing personalities start to complicate their work, and Chief Bogo threatens to separate them unless they resolve their differences. During a raid on a smuggling ring, Judy finds a piece of snake skin, although snakes have not been seen in Zootopia for years. Undeterred, she discovers that a snake may be at the Zootennial Gala, an event hosted by Milton Lynxley, whose grandfather Ebenezer founded Zootopia, to celebrate its centennial anniversary.

While infiltrating the Gala with Nick, Judy befriends Pawbert, the youngest son and black sheep of the Lynxley family. Meanwhile, a hooded creature infiltrates the party and reveals himself as a pit viper, who kidnaps Milton and uses him to steal an old journal that documents the creation of the weather walls that regulate Zootopia's climate zones. Judy corners the viper, who confesses the journal contains evidence to exonerate his family. Seeking to preserve his family's reputation, Milton demands to have the journal burned and the viper killed, but Judy refuses, setting the room ablaze. When ZPD Captain Hoggbottom witnesses the viper accidentally biting Bogo, the Lynxleys frame Judy and Nick for the crime, forcing them to escape with the journal whilst an unknown motorcyclist retrieves the viper. Afterwards, Milton orders Mayor Brian Winddancer to locate and subdue Judy, Nick, and the viper.

Nibbles Maplestick, a conspiracy theorist beaver, leads Judy and Nick, now fugitives, to Marsh Market, a secluded area of Zootopia where reptiles hide. There, a basilisk named Jesús explains that the reptiles' original district was buried during the construction of Zootopia's arctic district Tundratown, which is expected to expand to Marsh Market. The ZPD, led by Hoggbottom, finds Judy and Nick, who narrowly escape, but the viper reappears, retrieves the journal, and escapes through a water tunnel. As they attempt to locate the viper, the pair climbs to reach an abandoned lodge, leading to an argument that ends with their shared carrot pen breaking. Inside, Judy discovers that reptiles once lived peacefully in Zootopia. The ZPD corners them and arrests Nick, but the viper, who introduces himself as Gary De'Snake, and his motorcyclist partner, revealed as Pawbert, rescue Judy, explaining that Gary's great-grandmother Agnes was not only the original author of the journal, but also the true founder of Zootopia. Her greedy investor, Ebenezer, plagiarized her engineering work on the weather walls and later framed her for murdering his tortoise maid, who tried to stop him from burning the original patent. Her death subsequently turned the general populace against reptiles, eventually leading to their exile from Zootopia.

Aided by Nibbles, whom the ZPD also arrested, Nick flees prison and locates Judy at the Desert-Tundratown weather wall, where she, Gary, and Pawbert activate an old clock tower to find the buried reptile district, deducing that the patent is hidden in Agnes' house. However, Pawbert betrays Judy and Gary, revealing he intends to destroy the patent and earn his family's respect. He injects Judy with snake venom, throws Gary into the snow, and steals the antivenom. Arriving at the wall, Nick fights Pawbert for the antivenom and manages to throw it to Gary, who cures Judy. After emotionally reconciling with each other, Judy and Nick, accompanied by Gary and Nibbles, follow and subdue a barely-alive Pawbert, while Winddancer defeats the remaining Lynxleys. They then find both Agnes' house and the patent, and Pawbert reappears and attempts to destroy it, but Hoggbottom incapacitates him.

With their crimes exposed, the Lynxleys are arrested, while Judy and Nick are exonerated, Bogo recovers, and the Tundratown expansion to Marsh Market is cancelled, allowing for reptiles to be fully reintegrated back into the city. Gary reunites with his family, and Agnes is finally credited as Zootopia's true founder. Nick gifts Judy the newly repaired carrot pen before they begin tracking down the escaped convicts Nick accidentally released, starting with previous adversary Dawn Bellwether. Sometime later, Judy replays a recording on her carrot pen of Nick saying he loves her before her neighbors interrupt, arguing over whether she should stop playing the recording. After she leaves, something flies past her window and leaves a bird feather on her windowsill.
