Lucy is a gray Persian, who belongs to Laura Haruna's cousin Emiko.
In the episode Lovestruck Stucky, the Ham-Hams were in a search to find the bunny in Emiko's house. They were all in a room with Laura, Marian, and Emiko. To sneak to the other side of the room, some of the Ham-Hams hide inside a dollhouse and some moved it to the other side. Suddenly, Lucy approaches the dollhouse and frighten the Ham-Hams. Then Emiko notices Lucy and takes her away from the dollhouse.
