When Ash and friends step squarely into a trap, they’re soon surprised to learn it was set not by Team Rocket but by a man bent on capturing a Jigglypuff that lives nearby. They further learn that he’s been camped out in these mountains for the better part of six months in order to fulfill a promise to his daughter to catch this Pokémon for her as a birthday gift.  Unable to convince him that his daughter would prefer to have her father there on her birthday even without the promised Jigglypuff, Ash and friends commit to helping the father keep his promise. Time is short, though, as his daughter’s birthday is the very next day.
