Originally a wild Pokémon, Espurr came to Lacy's mansion. Lacy befriended Espurr and took it inside and played with it. One day, Lacy gave Espurr a pendant to remind it of her. Espurr treasured this pendant. Espurr came back one day and Lacy was not present. When the heroes and Team Rocket came, it played tricks on them, but soon befriended Bonnie and played with her. Team Rocket was not amused and went to take Espurr, who blasted them off. Elise, Lacy's granddaughter, arrived and explained that Lacy passed away. To pay respects, Elise took Espurr along.
