May is feeling the pressure at the Mulberry City Pokémon Contest, her last chance to get a fifth ribbon before the Grand Festival. To make things worse, Harley shows up! He has his ribbons already so he doesn't have to compete. But Jessie plans to enter in her Jessebella disguise, so when Harley spots Team Rocket, he offers to loan them his Cacturne and Banette to use against May in the Contest.
