The Pokémon Water War

Ash and friends arrive on an island to get something to eat, but those plans are interrupted by a warehouse fire. They try to help, but it's not enough. All of a sudden a group of Wartortle appear and put the fire out. Their trainer, Captain Aidan uses Squirtle, Wartortle, and Blastoise for fighting fires. Wanting to prove itself as strong as its evolution, Squirtle begins to train with Captain Aidan. Meanwhile, Team Rocket wants to capture all the firefighter teams for themselves.
