The Pokémon Water War (Japanese: ひけしたいけつ！ゼニガメＶＳカメール The Fire Extinguishing Showdown! Squirtle VS Wartortle!) is the 25th episode of Pokémon: Adventures in the Orange Islands.
Arriving at Ascorbia Island, Ash and co. encounter Team Wartortle lead by Captain Aidan, the local firefighter. Seeing that it's pride as a firefighter was shot, Squirtle whips out its sunglasses exclaiming that it's Squirtle Squad time. Misty explains to Tracey what the Squirtle Squad was, since it was before Tracey joined up, and Ash asks Aidan to train with him and he accepts. Later Team Rocket capture Team Wartortle, Squirtle and Pikachu. Can Ash and Captain Aidan retrieve their Pokémon before an apartment fire turns into a wildfire?
The heroes came to a city and Ash calls Lapras back. Ash complaines he is hungry and Misty says he is not the only one. Tracey tells they can go to an Art Museum, though Ash wants to see a Double Cheeseburger first. Suddenly, they see people running and hear there is a fire. They see a warehouse is on fire, so Misty gives Tracey her Togepi and goes with Ash to douse the fire. Misty sends Staryu and Ash Squrtile, who use Water Gun to douse the fire. However, it is not enough, but a fire fighter appears. A flaming column falls down, but Ash, Misty and their Pokémon get saved by Wartortle. Squrtile sees Wartortle with the scarf. The fire fighter blows a whistle, as the Wartortle line up and use Water Gun.
The building is burned out, but the fire is stopped. The heroes are grateful to the fire fighter, Captain Aidan and his Team Wartortle. Aidan shows them a tour of his teams - Team Blastoise (who douse bigger fires) and Team Squrtile (who extinguish places that are harder to reach). The Team Wartortle line up in his command, impressing the heroes, although Squrtile seems sad. Misty tells Ash Squrtile is disappointed it couldn't stop the fire by itself. Squrtile pulls out its glasses and puts them on. Ash explaines to Tracey Squrtile was in the squad that made trouble as they were abandoned by their trainers, although they got disciplined after stopping a fire, becoming heroes. Ash asks Aidan to test the strength of Squrtile in a battle. Aidan hesistates, but Ash manages to persuade him. Team Rocket see this and think about capturing Pikachu and Wartortle.
A marathon is commenced. Squrtile and Wartortle run, but Wartortle manages to gain the advantage. Squrtile speeds up, but trips over a rock and gets rolled out. Squrtile rolls over Wartortle, who also rolls out and they go past the line. Tracey sees they set a new record. Aidan is impressed and offers a day of Squrtile in the Wartortle training programme. Aidan launches frizbys, which the Wartortle push using Water Gun. Aidan sets higher and faster, but the Wartortle leader and Squrtile manage to hit it. The training is over, but a frizby levitates. The Wartortle and Squrtile go to hit it and follow it, but fall in a hole. Team Rocket emerge and take the Team Wartortle and Squrtile with them. Meowth takes Pikachu using robotic arms and Jessie places it in a cage. Pikachu uses Thunderbolt, but the electricity is absorbed to power up a fan. James sends Weezing, using Smokescreen as a distraction. Tracey sends Scyther, who uses Swords Dance to gust out the smoke. Scyther gets exhausted, while the gang sees Team Rocket is gone.
Team Rocket see the Wartortle and think of bringing it to the boss. James tells they don't have to send every Wartortle and thinks of taking one for himself. Jessie counts and chooses one, but James tells he should pick first as it was his idea. Jessie and James argue. Meowth goes to feed Wartortle, but gets pounded by Jessie. Meowth scratches them, wanting to prove he is also important, but gets in a fight with Jessie and James. During that, Wartortle and Squrtile make a plan. As Venonat tracks, Aidan receives a call from Jenny, as there is a fire in the city. With Team Blastoise attempting to move the truck, Team Squrtile are trying to douse the fire but are not powerful enough. Misty tells she can get there and help. Tracey sends Marill and Scyther for additional help. Misty goes away, while Ash, Aidan and Tracey go to the place where Venonat sees Team Rocket.
Team Rocket bicket who should get the Wartortle. Wartortle and Squrtile use Water Gun to fill the shack with water, causing Team Rocket to be swept out. The Wartortle and Squrtile roll out in the net to move, passing near Team Rocket. Meowth goes to scratch them, but Squrtile and Wartortle withdraw, causing Meowth to free them by scratching the net. Tracey, Ash and Aidan appear, with Venonat tackling Team Rocket, knocking them out. Ash frees Pikachu, but Team Rocket still want to battle. Jessie sends Arbok and James Weezing. Squrtile and Wartortle push them away using Water Gun. With Pikachu's Thunderbolt, Team Rocket are blasted off. As Misty watches their efforts to douse the fire are not efficient, a burning object falls on her. However, the Wartortle and Squrtile use Water Gun to destroy ie before it lands on her.
Ash, Tracey and Aidan appear. They hear a child shouting for help. Ash goes to save it, but Aidan holds him, as it is too risky. Instead, Squrtile puts its glasses on and goes with Wartortle to save the child. Hopping on the cannons, they come to the building after Blastoise launches them using Hydro Pump. They get the child and douse the fire to get out. Wartortle falls down in rubble, but Squrtile gets it and pulls it up. A door falls on Squrtile, but Wartortle uses Water Gun to push the door away. The heroes get worried as Squrtile and Wartortle are in the building for a long time, but they appear out of the building and jump to them. After the fire is extinguished, the child hugs his mother, while Squrtile and Wartortle shake hands.
Next day, Ash tells they are headed for the next island by using a ferry in the next town. Before departing, Squrtile and Wartortle shake hands, as the heroes acknowledge their friendship. The gang waves goodbye
