Zootopia 2

One week after Judy Hopps and Nick Wilde became partners at the Zootopia Police Department (ZPD), their clashing personalities start to complicate their work, and Chief Bogo threatens to separate them if they cannot resolve their differences. During a raid on a smuggling ring, Judy finds a piece of shedded snake skin, but when she shares her discovery, her worries are dismissed because snakes have not been in Zootopia for years. Undeterred, Judy finds evidence that a snake may be present at the Zootenial Gala, an event celebrating the city's centennial anniversary, hosted by a family of lynxes who are descendants of Zootopia's founder, Ebenezer Lynxley.

At the Gala, Judy befriends Pawbert, the youngest son and black sheep of the Lynxley family, while Nick notices a hooded figure, revealed to be a pit viper named Gary De'Snake. As chaos erupts, Gary kidnaps Milton, the Lynxley patriarch, and uses him to steal an old journal that documents the creation of the weather walls that regulate Zootopia's climate zones. Judy corners Gary, who persuades her that snakes are not bad animals and that the journal contains evidence to help his family. Seeking to protect the Lynxley reputation, Milton demands to have the journal destroyed and Gary killed. When Judy and Nick do not comply, the Lynxleys accuse them of aiding Gary to have them arrested, with witnesses holding them responsible for Gary accidentally biting Bogo. Judy and Nick escape with the journal, while an unidentified motorcyclist takes Gary.

Now fugitives, Judy and Nick are rescued by Mr. Big and Fru Fru, but decline their offer to lay low and seek help from Nibbles Maplestick, a conspiracy theorist beaver knowledgeable about reptiles. Nibbles leads them to Marsh Market, a secluded area of Zootopia where reptiles hide. There, they meet a basilisk named Jesús, who explains that the reptiles' original district was buried during the construction of Tundratown, the arctic district of Zootopia.

Gary takes the journal and escapes through a water tunnel, with Judy and Nick following him. After ejecting from the tunnel, Judy and Nick ascend a mountain to reach an abandoned lodge, where they uncover evidence showing that reptiles once lived peacefully in Zootopia. They also get into an argument that results in their shared recorder pen breaking, causing them to have a falling out. The ZPD officers chasing them catch up and arrest Nick, but Gary and the motorcyclist, who turns out to be Pawbert, rescue Judy. After escaping, they learn that Gary's great-grandmother, Agnes, authored the journal and was Zootopia's true founder, but Ebenezer stole the credit and framed her for murdering his tortoise maid, who had tried to stop him from destroying the weather walls' original patent. Since then, snakes have been viewed as dangerous creatures, and all reptiles have been banned from Zootopia.

Nick, along with numerous other criminals, escapes from prison with Nibbles' help, and they locate Judy at the weather walls. There, 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 earn his family's respect by destroying the patent. He injects Judy with snake venom, throws Gary into the snow, and steals his antivenom pen. Arriving at the weather walls, Nick fights Pawbert for the pen and throws it to Gary, who cures Judy. Nick and Pawbert fall off the wall, but Judy saves Nick with Gary’s help, and they mend their friendship by opening up about their emotional insecurities. Having survived the fall, Pawbert reaches the Lynxley manor and reveals his plan to his family, but the group catches up and defeats the Lynxleys with help from Mayor Brian Winddancer. Reaching Agnes' house, Judy, Nick, and Nibbles help Gary find the patent, and Pawbert makes a last-ditch attempt to destroy it, but ZPD officers arrive and knock him out.

With their crimes exposed, the Lynxleys are arrested, and Judy and Nick are cleared of all charges, while Bogo recovers from the venom and reptiles reintegrate into the city. Gary reunites with his family, and Agnes is credited as the true founder of Zootopia. Nick gives Judy the newly repaired recorder pen before they go on to recapture the escaped criminals.

Some time later, Judy replays a recording of Nick saying he loves her before her neighbors interrupt. After she leaves, a feather lands on her windowsill.
