 On their way to Saffron City, our heroes come to the spot where Butterfree gather to find mates and travel together across the sea in order to have babies. Ash lets out his own Butterfree and helps it to try and find a mate of its own. It eventually finds one, a uniquely pink Butterfree, and attempts to impress it. However, Butterfree is rejected immediately and flies off heartbroken. The group help Butterfree to be more confident and try again, but to no avail. To make matters worse, Team Rocket enters in a brand new chopper and net just about every Butterfree, including the pink one. Ash s Butterfree chases after them as our heroes follow, but will it be able to stop Team Rocket on it s own and save its beloved? And when the time comes, will Ash have the courage needed to finally say good-bye?
