From Bulbapedia, the community-driven Pokémon encyclopedia.
Madison (Japanese: エル Elle) and Alexa (Japanese: リサ Lisa) were the characters of the day in The Kecleon Caper.
They are a pair of rich young sisters who are traveling the world in the massive Blue May, a luxury blimp. They dress in fur coats and each have a Kecleon. Brock later helped their Kecleon recover from motion sickness.

| Madison and Alexa each own a Kecleon, Madison's being Reddy (Jp: アズキちゃん Azuki-chan) and Alexa's being Greeny (Jp: ミドリちゃん Midori-chan), respectively. The two Kecleon like to steal things to cause people to play hide and seek with them. The Kecleon had motion sickness when Ash and his friends saw them. Shortly afterward, Brock gave them some medicine and home-made Pokémon food, and they became well again.
When playing in their room, Greeny spotted Meowth with Alexa's jewelry box, and it quickly uses its tongue to snatch it from him. Later the Kecleon go missing and the group try to find them; Team Rocket are pursuing the Kecleon, which are running all around the ship. The Kecleon are able to escape, and in the end, Team Rocket are sent blasting off. Madison and Alexa gain trust in their Kecleon.
Reddy and Greeny's known moves are Lick and Psybeam, and their Ability is Color Change.
