Pokemon the Series Season 9 Episode 21 Curbing the Crimson Tide!

Ash and his friends, Pikachu, Brock, and May, head to a port where they plan to take a ferry to their next destination. However, when they arrive, they find the city overrun with wild Crawdaunt causing havoc everywhere. They soon discover that the cause of the problem is a group of local kids who have been catching and training the Crawdaunt for their own purposes.

Ash and his friends decide to intervene and try to stop the kids from using the wild Pokemon for their own gain. They quickly find that the task won't be easy, as the kids have become very attached to their Pokemon and refuse to give them up. Meanwhile, Team Rocket is also in the area, hoping to use the chaos to their advantage and capture some Pokemon of their own.

As Ash and his friends try to convince the kids to release their Pokemon, they are interrupted by a group of trainers, led by a woman named Trinity. Trinity believes that the Crawdaunt are dangerous and should be culled to prevent further destruction. This leads to a debate between Ash and Trinity over the treatment of Pokemon. Ash believes that the kids should be taught to respect and care for their Pokemon rather than simply disposing of them, while Trinity argues that wild Pokemon are a menace that need to be eliminated.

The situation escalates when Team Rocket gets involved and steals the wild Crawdaunt, hoping to use them for their own purposes. Ash and his friends team up with Trinity and the kids to stop Team Rocket and save the Crawdaunt. During the battle, Ash's Pikachu is severely injured but the group is eventually able to defeat Team Rocket and return the Crawdaunt to the wild.

After the battle, Trinity has a change of heart and decides to help the kids learn how to train and care for their Pokemon properly. The episode ends with Ash and his friends departing from the city, leaving behind a group of new friends who have learned a valuable lesson about the importance of treating Pokemon with respect and compassion.
