He then wakes up from his nightmare on his birthday and the animals present him with a miniature model of New York City made out of mud.

Carl Fredricksen is a young 8-year-old boy who idolizes famous explorer Charles Muntz. Muntz has been accused of fabricating the skeleton of a giant exotic bird he says he discovered at Paradise Falls, and vows to return there to catch one alive.

Carl and Ellie eventually get married and live together in the restored house. After suffering a miscarriage and being told they cannot have another child, the two decide to realize their dream of visiting Paradise Falls.

As a cub, Alex the Lion was called Alakay and was the son of Zuba, the alpha lion. Though Zuba tries to teach Alakay to be a hunter, the cub is more interested in dancing, and is captured by poachers when Makunga, Zuba's rival, challenges Zuba to a fight for the position of alpha lion. Alakay is forced into a crate, and taken away despite Zuba's attempts to rescue him. The crate falls into the ocean where it drifts to New York. There, Alakay is renamed Alex and sent to the Central Park Zoo where he grew up, meeting Marty the Zebra, Melman the Giraffe, and Gloria the Hippopotamus. Most of the events of the first film are then described through a series of news flashes.
At the Central Park Zoo, Marty the zebra is celebrating his tenth birthday, but longs to see the rest of the world from outside his pampered life at the zoo, believing that he can find wide-open spaces to run around in, like in Connecticut. Marty's best friend, Alex the lion, attempts to cheer up his friend by singing Frank Sinatra's "New York, New York" with him. Still unsatisfied, Marty gets some tips from the zoo's penguins: Skipper, Kowalski, Rico, and Private. The penguins are similarly trying to escape the zoo. Marty's friends — Alex the lion, Melman the giraffe, and Gloria the hippopotamus — realize Marty's folly and try to follow him. The four, along with the penguins and the chimpanzees Mason and his silent friend Phil, eventually find themselves at Grand Central Station, but are quickly sedated by tranquilizer darts when Alex's attempt to communicate with humans is mistaken for aggression. The zoo, under pressure from animal-rights activists, is forced to ship the animals, by sea, to a Kenyan wildlife preserve. During their travels, the penguins escape from their enclosure and take over the ship, intent on taking it to Antarctica. Their antics on the bridge cause the crates containing Alex, Marty, Melman, and Gloria to fall off the boat and wash ashore on Madagascar.

While the males struggle through the harsh winter, Memphis briefly drops the egg. The resulting chick, Mumble, is unable to sing but can tap dance. Nevertheless, he is enamored with Gloria, a female penguin who is regarded as the most talented of her age. One day, Mumble encounters a group of hostile skua, with a leader who is tagged with a yellow band, which he says is from an alien abduction. Mumble narrowly escapes the hungry birds by falling into a crevice.

A dust speck is dislodged from its obscure place and sent adrift through the Jungle of Nool. At the same time, Horton the elephant (Jim Carrey), the jungle's eccentric nature teacher, takes a dip in the pool. The dust speck floats past him in the air, and he hears a tiny yelp coming from it. Believing that an entire society of microscopic creatures are living on that speck, he places it atop a clover. Horton finds out the speck harbors the city of Whoville and its inhabitants, the Whos, led by Mayor Ned McDodd (Steve Carell). He has a wife, Sally (Amy Poehler), 96 daughters (whose names all begin with the letter H), and one teenage son named JoJo (Jesse McCartney). Despite being the oldest and next in line for the mayoral position, JoJo doesn't want to be mayor, and because he's so scared of disappointing his father, never speaks. Once Horton begins carrying the speck with him, the city starts experiencing strange phenomena (earthquakes and changes in the weather), and the Mayor finds his attempts to caution Whoville challenged by the Town Council, led by the opportunistic yet condescending Chairman (Dan Fogler).
