Pokémon - Season 9 Episode 39 Overjoyed! Gotta catch 'em all!
Overview: Ash has reached Fennel Valley at last, where he plans to challenge Brandon to an official battle—but Brandon won't be back until tomorrow! Instead, our hero is welcomed by an enthusiastic Nurse Joy. This Nurse Joy loves Pokémon battles and Contests, and she even offers to help Ash train. Her Chansey may look sweet, but once its nurse's hat comes off, so do the gloves! Chansey quickly outpowers Ash's Corphish, teaching Ash a lesson about battle strategy that doesn't make him too happy.
