Ape Escape 3 (サルゲッチュ3 Saru Getchu 3) is a platform video game published and developed by Sony Computer Entertainment for the PlayStation 2 video game console.
Specter, the Pipo Monkeys' leader, finds a Monkey Helmet, and hires the human scientist Dr. Tomuki (Dr. Tomoki in the U.S. version) to aid him in his evil plans. They establish television stations protected by the Freaky Monkey Five where they plan to broadcast TV shows worldwide. The television shows that are broadcast on every television put every human except the twins, Satoru and Sayaka (Kei and Yumi), their aunt Aki, and Natsumi (Natalie) into a mindless trance. When Natsumi informs Satoru and Sayaka that Kakeru (Spike), Hikaru (Jimmy) and the Professor were all infected by the television show, Satoru and Sayaka go out to catch the monkeys and thwart Specter and Tomuki.
Their mission was to go to every movie set and capture all the monkeys there and destroy the satellite there. Satoru and Sayaka easily capture White Monkey, Blue Monkey, and Yellow Monkey. When they reach the TV Station where Pink Monkey is, Satoru and Sayaka's attempts to capture her fail and she escapes. They manage to capture Red Monkey afterwards.
When they reach Tomuki City, Tomuki challenges them to a battle in his giant Tomo-King robot. Tomuki, after being defeated by Satoru and Sayaka, and being humiliated by Specter, lets them take his rocket to space to defeat his former partner. Once they reach Specter's outer space base of operations: Space Station SARU-3, they capture all the monkeys and deactivate the movie sets on their way to Specter. When they reach Specter, he tells them his plan about how he will use his space station to cut the earth in half and keep half of it for the monkeys (leaving the other half, originally meant for Tomuki, to the humans). Afterwards he gets in his new Gorillac Mech and tries to activate his plan. He is defeated and the two escape from the satellite, leaving Tomuki to give his life to deactivate the Twin Heavens. He survives. After Specter is defeated, Pink Monkey releases him and the rest of the Freaky Monkey Five, leaving them to be caught again in extremely similar missions. To complete the game one hundred percent, all the four hundred and forty-two monkeys have to be caught, all the time trials have to be completed with a gold time, and all the items, CDs, Video Tapes (except 28), Car Skins, Genie Dance tracks, books, etc. have to be bought. The game holds a total of four hundred and thirty-four monkeys if the secret code monkeys are not caught.
