Grooming Furfrou!

When they arrived at the next city, Serena informs Ash & Co. that there is a special Star Groomer in the city. This groomer has got an apprentice who is having some troubles; the Furfrou she has to groom doesn't approve of her, and just refuses to be groomed. However, when some new groomers come in, and offer to groom the group's Pokémon, things are not what they seem. Will Ash & Co. be able to protect their Pokémon and help the groomer to groom Furfrou?
