Rio 2

Three years after the attempted smuggling incident in Rio de Janeiro, Blu and Jewel raise their three children, Bia, Carla, and Tiago. Meanwhile, Blu's owner Linda and her husband Túlio are on an expedition in the Amazon and, after falling down a waterfall, discover a blue Spix's macaw when a feather floats down towards them. When words about the encounter are broadcast through television, Jewel, who thinks that Carla, Tiago and Bia are becoming too domesticated, believes that they should go to the Amazon to help find the other blue macaws. While the kids are ecstatic, Blu is uncertain but is pressured into going along. Their best friends Rafael, Nico and Pedro also decide to come along to scout talent for Carnival.

Big Boss, the leader of a group of illegal loggers, discovers Linda and Túlio's expedition to find the macaws and orders his henchmen to hunt them down. Meanwhile, Blu and Jewel's old enemy Nigel, who has become flightless, plots to exact revenge on Blu with the help of his new comrades, Charlie an Tamandua and Gabi, a poison dart frog who is in love with him. After arriving at the jungle, Blu, his family and their friends are taken to a flock of blue macaws that hide in an uncharted section of the Amazon.

There, Jewel is reunited with her long-lost father, Eduardo, paternal aunt Mimi and childhood friend Roberto. Eduardo seems unimpressed at first with Blu but thanks him for returning Jewel home. Having lost their previous habitat to arson from the loggers, Eduardo distrusts humans, and brushes off Blu's suggestion to expose the sanctuary to Linda and Túlio to ensure their protection.

While searching for the macaws, Linda and Túlio are captured by the loggers. Meanwhile, Blu does his best to fit in with the flock as his family is doing, but his continued reliance on the tools he brought prevents him from connecting with anyone. In another attempt to get closer to him, a disguised Nigel named Bob, wins a talent show to become a performer for a Carnival show that Rafael, Pedro, Nico and Carla are hosting. When Blu tries to pick a Brazilian nut for Jewel, he accidentally puts it in the territory of the Spix macaw's enemies, the scarlet macaws, led by the hostile Felipe.

Blu inadvertently causes a war for food between the two tribes when he accidentally swats Felipe with a branch. The war turns out to be a football match, but Blu costs the flock their territory when he accidentally scores on his team's own goal.

After a heated argument with Jewel, Blu decides to leave Linda and his human roots behind him for his family's sake, but after witnessing the loggers' destruction of the forest, he returns and rallies the flock, reconciling with Jewel. With Blu's knowledge of human technology and help from the scarlet macaws, the flock, with the rest of the jungle animals, disable the loggers' machinery. In the chaos, Eduardo encounters a tractor but is rescued by Linda and Túlio. Big Boss tries blowing up the trees with dynamite, but Blu thwarts him.

Nigel intervenes, leaving Big Boss to get eaten alive by an anaconda. Wanting Blu to himself, Nigel attacks him. While Gabi tries to help, she accidentally shoots Nigel with a porcupine's quill filled with her poison, but Bia reveals that she is actually a tree frog. An overjoyed Gabi smothers Nigel with affection and drags him away, while Charlie leaves.

With the flock under Linda and Túlio's protection, Blu and Jewel decide to live in the Amazon with their kids, although they decide to spend their summers in Rio. Eduardo drops his anti-human stance and proudly accepts Blu into the flock, Charlie decides to stay in the Amazon, Luiz the bulldog finally arrives in the Amazon, and Nigel and Gabi are sent to Rio for study.
