Ep 20. Brave The Wave

Ash and his friends land in an island which is going through a severe water crisis. The island's river has dried up causing depletion in the water supply. The mayor of the island, who is a loyal Pokemon trainer, seeks Ash's help to solve this problem. The group then decides to split up and search for the source of the dried-up river.

During their search, the group discovers that the river has been redirected by Team Rocket's dam. They also learn that the dam is incomplete and is about to burst, which can result in floods and can cause serious damage to the village. The group then devises a plan to stop the dam from breaking.

However, Team Rocket is not going to make it easy for them. They send out their Pokemon to fight with Ash and his team. Ash trots out Pikachu to fight Team Rocket's Meowth, the battle occupies the screen with electric attacks and thunderbolts, and with Ash's quick thinking, Pikachu defeats the Meowth, and Team Rocket retreats.

Meanwhile, the group has discovered the location of the dam's weak point and rushes to stop it from bursting. They use their Pokemon and work together to stop the water from flooding the island. The tension builds as the dam starts to crack, but Ash and his friends manage to block it with rocks and debris around the area.

As the danger finally subsides, the group learns that the river has returned to its natural course, and the water supply on the island has been restored. The townspeople thank Ash and his team for their heroic actions, and the mayor rewards them with badges for their pokemon.

In the end, the group is seen bidding goodbye to the town and promising to come back and visit someday. They then continue their journey to the next destination, hoping to help people and pokemon alike.
