Oddworld: Munch's Oddysee is a 2001 video game, released for the Xbox. It is the third game made by Oddworld Inhabitants, the second chapter of the Oddworld Quintology, following Abe's Oddysee, and the third overall Oddworld game.

Originally announced as a title in development for PlayStation 2, it was instead released exclusively as one of the launch titles for Xbox. While an "Oddboxx" containing the first four Oddworld games was originally intended for a holiday season 2009 release on Steam, the fourth game in the series was not released until December 20, 2010 on Steam, over two years after the first three. The game received generally positive critical reviews around the time of game's release. Though retrospective and reviews of the game's ports has been more mixed to negative.

Following the destruction of RuptureFarms and SoulStorm Brewery, the Glukkons commercially harvest the froglike Gabbits nearly to extinction, harvesting them for their eggs, to create a caviar-based delicacy called "Gabbiar", and their lungs, needed to replace their own because of their excessive chain-smoking habit. Munch, the last surviving Gabbit, is captured and brought to Vykkers Labs, a floating research fortress, where the Vykkers prepare to convert him into a slave to find animals for them, to allow them more time for their research. After having an electronic device attached to his head for that purpose, Munch finds he can use it to help break free captured Fuzzles, who help him to break free from his own confinement. At the same time, the Mudokon hero Abe is instructed by the "Almighty Raisin", an ancient oracular creature, to find and rescue Munch upon learning of his predicament. Abe reaches the Lab, just as Munch manages to escape via a waste chute, and work together to return to the Raisin.

Upon returning to see him, the Raisin reveals that both need to work together to get back into Vykkers Labs, where Abe can find the eggs of unborn Mudokons that he needs to save. Although not willing to return, Munch learns that the only way to save his species from extinction is to recover the last can of Gabbiar in existence, which is due to be auctioned in the Labs. The duo discover that the only way to infiltrate the Labs and the auction is to assist a lazy Glukkon named Lulu, who desires to achieve a fortune from other Glukkons and elevate himself to the highest social rank amongst his species. To assist in this, the duo track down and force various wealthy Glukkons to donate their money to Lulu's accounts, swiftly making him a multi-millionaire. Lulu then heads to Vykkers Labs to bask in his new-found fame and wealth, to which Abe and Munch use the opportunity to break into the Labs. What happens next depends on the overall level of Quarma the player has attained by this point
