Chase and the Rebel gang are forced into battle with a pack of angry Foodons known as the Pork Platoon. With help from Chef John and Coco, the Rebels fight off the swine onslaught, but not before Oslo tumbles over a cliff and disappears. The group takes refuge in the mountain village of Hamsterdam, where they're shown an ancient treasure chest left behind by the legendary "Grub Guru". A mysterious fortune teller warns that King Gorge's reign will not end until the Guru returns, but she senses he is near. When the villagers are struck by the nasty Swine Flu, the Pork Platoon moves in, morphing into the giant Foodon, Slop Suey. As Chase tries to whip up a cure, the Rebels fight off Slop Suey, but can they protect the village and the ancient treasure chest from falling into the Gluttons' greasy hands?
