Million Monkeys[a] is a 2006 platform video game developed and published by Sony Computer Entertainment for the PlayStation 2 as part of the Ape Escape series.
The professor's computer program in the form of the character "Chall", alerts them of the disaster happening in the city.
Once Specter has been defeated, monkeys run wild throughout the city, and the game takes a turn in a different direction, and the player is left to save the globe from being destroyed by mutant creatures around the world.
Once the impostor is defeated, it's revealed it was a Pipotron called "Meta" and it can take form of any living creature.
The more the players capture, the more "Gotcha Points" get added to their total score, which helps to unlock certain items in various ways.
They added: "Take the beauty of butterflies, a few hundred monkeys out of your mind and mix well with a simple yet innovative game play and graphics up to date.
Bake for a few minutes in a preheated oven of Sony Computer Entertainment, and voila, here is Ape Escape!"
