After leaving Eterna City, Ash, Dawn, and Brock travel down Cycling Road to Hearthome City, the location of the next gym and contest. Soon Brock's egg begins to glow, so they head to a nearby Pokémon center. Then they get there it seems to be abandoned. However, Nurse Joy and Chansey are there, but Nurse Joy acts extremely sad since her center has looked like a dumped ever since Cycling Road was built, and she thinks she is no longer needed since no one stops by. They try to cheer her up (as well as eventually help her restore the center), since they need her to help with Brock's egg. In the center, the egg finally hatches into Happiny. Brock and Happiny instantly take a liking to each other, and Brock gives her a bath and starts to work on a stone for her to hold. Meanwhile, Team Rocket is lurking around the center and plan to steal Happiny so they can evolve it into Chansey and run their own hospital and become rich. (thetvdb.com)
