The film opens with a pickpocketing monkey named Leroy who tells his nephew, Krel how he met the Penguins of Madagascar. a English Mastiff named Sniffer was the partner of an archaeologist, Green Thomas, who retrieved one half of a dial which would lead to Queen Cleopatra's tomb. He never found the other half and retired. The scene then switches to present New York City where Green is giving his grandson, Ishan a tour of the Egyptian exhibit at the museum. The penguins, Skipper, Kowalski, Rico and Private are also at the exhibit. Ishan stays behind with his grandfather who gives his puppy, Sniffer's bandanna. A British archaeologist, Devante along with his cat, Nuggent meets Green in his office and reveals to have the other half of the dial, and insists on bringing him and Ishan along for the ride, but refuses to bring along his puppy due to certain allergies. Fortunately, the penguins stowaway in Devante's DC-3 Douglas airliner via a box of TNT.

Green, Ishan and the penguins enter the town of Bastati in a truck. Rico farts after eating some TNT and Philippe and Mike run away frantically, afraid that it might explode. While exploring the marketplace, Ishan meets a native girl named Elly. When he introduces himself, Elly does not understand him but it is revealed that she does know and speak English when she tells him that he called her a cucumber when Ishan tried to speak Arabic. The penguins split up to find Green and Ishan. A woman at the marketplace gives Kowalski a hijab and Rico is given a kebab. Leroy steals the kebab from Rico and he is blamed by the penguins for stealing the kebab. Leroy tells them that he was just trying to take it because he might choke on the bones. Leroy agrees to help find Green and Ishan and gives Skipper a fez and the penguins a place to sleep in a warehouse stable.

A stolen Camel named Hammy is sent in by a camel thief and the penguins ask Hammy why she is sent there. She explains that she was stolen by a group of camel dealers and sent to the town to be sold to people at an auction. They agree to help her find her Bedouin tribe. Meanwhile, Leroy spies on Green, Ishan, and Devante trying to solve the riddles and puzzles in order to find the lost tomb of Cleopatra. Green connects two halves together and puts them in the hole, causing the tip of the obelisk to rotate facing the moon and the light of the moon to light the way. Leroy tells the penguins that they are heading to the oasis. In the morning, Leroy rips off a hose from their truck to delay Devante from heading there first. As they leave, Hammy spits digested food or "gnarly loogey" as Private calls it, at the camel dealer and they start leaving for the oasis. Leroy hitches a ride on the truck to the desert.

At the oasis, Thomas tells the story of Cleopatra, the cat god Dular gave a special necklace called "The Cat's Eye Necklace" to her. Her cat Cleocatra was angry that Dular gave the necklace to a human, so she decided to steal the necklace. A dachshund named Valiant saw Cleocatra, so he informed Cleopatra what was going on. Cleopatra was so triggered and enraged at her trusted cat, so she decided to use the necklace to make dogs man's best friend, and cats were banished from the palace. Ishan thanks Green for bringing him on the adventure. Meanwhile, they realized that fate sent them on the adventure and journeys have deeper meanings as they go to sleep. In the morning, Elly surprises Ishan by hiding behind a well, and Amir asks Ishan if Green knows him well. He says that he met him a few days ago and Amir tells Ishan to tell Green that he should not be trusted.

In the morning, they start looking for clues. They brush off sand revealing the Cat's Eye symbol. Leroy spies on them opening the door into the well. Inside, they wipe off a symbol of royalty and the menet. Meanwhile, Leroy pokes a hole in their tire with a knife to delay them more. Nuggent catches Leroy and he runs away. The Bedouins start leaving the oasis. Private starts hallucinating from dehydration that a picnic is there and starts rolling on the sand. Kowalski says "That's what I call out in the cold!" and asks for a rimshot but there's no rimshot. Rico spots an oasis and start heading there for water. They find the stairway entrance to the well and start splashing around. As they come out, dates start falling on them, they realize Leroy is shaking the tree and they are glad to see him. Skipper asks where Green and Pete are located and says they are on the way to the oasis. Devante's car suddenly stops and he blames Seti and Tarik on the flat tire. Meanwhile the Penguins make it to the Bedouins and Hammy is reunited with her mother Amy. At night they watch the tribe dance and eat a feast.

At night Ishan overhears Devante talking about getting rid of Green and him so that the treasure will be theirs. Remembering what Amir said about Devante, he races to the tent and wakes up Green and tells him about Devante. Devante comes into the tent saying that Green will do whatever he says and Green says that he is done helping him. In the morning, the tribe makes a hot air balloon in order so they can find Green and Ishan. Ishan spots the balloon but Green keeps Devante from discovering by saying that there are no baboons in the desert. The penguins and Leroy attempt to land in the desert and land on a sand dune, falling in fast motion into the sand. They enter the temple and make it in time to escape a sandstorm.

Devante, Green, Ishan, Seti, and Tarik make it to the tomb while the penguins and Leroy are inside the tomb facing booby traps and various stuff including a giant game of senet and a quicksand trap. Nuggent finds out that the penguins are already there and chases after them. Private is saved from the pit of snakes at the giant game of senet but Seti is eaten by the snakes in the pit. The penguins make it into the tomb, Private starts wearing the Cat's Eye Necklace and starts acting like a cat. The statues start to come to life and Nuggent commands the cats to chase the penguins. Two of the cats fall into the pit of snakes and another two Budderball traps in the scarab beetle chamber. The last group of cats are eaten by a cobra.

Phillip, Green, and Ishan make it to the tomb chamber and Nuggent scratches Devante's face because she didn't want Phillip to take it. She starts wearing the Cat's Eye Necklace, and becomes ruler of the cats only to be turned into stone by the tomb because of a curse that any cat that wanted power would gain everlasting life in the form of a statue. A door opens with riches inside and Devante is wowed by it and wants to steal it. Phillip then challenges Thomas to a fierce duel. Devante is about to win when Ishan knocks him out with a shield. Devante regains conscience and escapes with the Cat's Eye Necklace and is chased by the Penguins. Leroy gets on Phillip's head and bangs it multiple times, making Devante drop the Cat's Eye Necklace. Hammy spits at Devante's face and is captured by the Bedouins, tied to a camel and (per request) is placed under the custody of the British embassy. At a dance in Bastati, Amir congratulates Green and Ishan for helping to find the Cat's Eye Necklace while Elly shows Ishan some of the moves the dancers make. At the museum opening, Thomas and Peter are declared national heroes along with the penguins, and Amir and Elly clap for them at the grand opening. The collar is put on permanent display in the museum in New York. Krel believes him to have exaggerated the story but Leroy smiles and takes out Cleocatra's collar from a mummy coffin behind him, revealing he stole it from the Fernfield museum.
