Lily (ボタン Botan) is Misty's sister and one of the Cerulean City Sisters. She is the second youngest of the four sisters. She sometimes appears in Pokémon Chronicles. She has participated in water plays with her sister, Violet. Lily usually teases Misty about her being the youngest of her siblings.
Lily is cheerful and childlike, and is the most carefree of the four sisters. Lily loves to wear cute clothes. She doesn't like to do battles, and prefers to buy clothes or acting roles in plays.
As demonstrated in the episode Misty the Mermaid, she wanted to play the role of the mermaid, and not a pirate, but when Misty left, she and Violet take turns playing the mermaid. She was voiced by Megan Hollingshead in the English Dub.
The Sensational Sisters's multiple Goldeen inhabit the pool in the Cerulean Gym along with many other Water Pokémon. They first appeared in a water performance called "Underwater Ballet" swimming with the other Pokémon alongside Misty playing the mermaid, then pretend to go to sleep. When Team Rocket take over the show they get the Goldeen trapped in a net. In the end with the help of Ash and his friends including Seaking and Dewgong they are able to get the Goldeen free. It is later seen in the finale of the performance.
Three make a brief cameo in Cerulean Blues in the aquarium.
