Pokemon Crystal the water ballerina border collie episode.

While showing his new friends of alola the cerulean city in kanto, Ash and Pikachu saw a crying, baby border collie named Crystal. The black and white puppy wants to join Misty's sisters in a synchronized swimming show, which was coming up in a few days, in the cerulean city gym. But the girls tease her and think that the pup can't swim in the water. So Ash, Pikachu, and their friends help her out. Lilie even made a special, pink, waterproof, puppy-sized tutu for Crystal to dance in the water.
