Lisa is a four-year-old girl living near Saffron City. For her fifth birthday, she told her father Mitch that she wanted a Jigglypuff for her birthday. He spent months looking for one, and at one point, he told her he probably wouldn't make it home for her birthday.
Eventually, he made it home, but Lisa was sad to see that he didn't bring home a Jigglypuff like she wanted. However, when he told her about how hard he worked to find one, she understood, and immediately fell in love with her dad's Loudred. Suddenly, the Jigglypuff appeared at their home, angry at Mitch for leaving it. However, it immediately fell in love with Lisa, and agreed to stay with her and play.
Mitch's daughter, Lisa, wanted a Jigglypuff for her birthday so Mitch took some time off of his job to find one. However, this Jigglypuff was hard to catch as every catch kept on being unsuccessful every time. With the help of Ash and his friends, Mitch was able to catch one as it was placed in a sound-amplified room. However, seeing that it was better off in the forest, Mitch decides that it was best to leave it there. He heads home and tells Lisa about the Jigglypuff. However, the Jigglypuff followed him home and Lisa became very happy, thus decided to stay with the family.
