Ep 47. Just Add Water

Ash and his friends are headed towards Pacifidlog Town, and on the way, they find a girl named Minnie who is looking for her lost Wingull, Peeko. They offer to help her search for Peeko, and Minnie tells them that she last saw Peeko near a nearby island. The gang reaches the island but finds that it is uninhabited and filled with strange rock formations.

While searching for Peeko, they come across a strange old man who asks them if they want to learn the ancient art of Wailord calling. The gang agrees, and the old man teaches them a song that supposedly calls the massive Water-type Pokemon, Wailord. The gang doesn't believe it will work but decides to give it a try.

After performing the song, they hear a faint sound from beneath the water, and they find that it is a group of Wailord swimming towards them. At the same time, a group of Sharpedo appears and tries to attack the Wailord. Ash and his friends jump into action and help the Wailord fend off the Sharpedo.

The gang realizes that the Sharpedo are after the Wailord's food source, a group of Corsola living on the nearby coral reefs. They decide to stop the Sharpedo by building a barrier around the Corsola. The gang manages to fend off the Sharpedo and saves the Corsola.

Ash and his friends continue their journey towards Pacifidlog Town, while Minnie is happy to have found Peeko and thanks them for their help.
