While training for his Gym Battle at Nimbasa City, Ash and co. encounter a Cottonee along with more Cottonee that are paired up. They soon realize that it's mating season for Cottonee, but the Cottonee Ash and co. encountered is the only one that didn't pair up. So Ash and co. decide to help it. Elsewhere, Team Rocket has plans of their own for the Cottonee. Will Cottonee find his true love, or will Team Rocket ruin everything?
