The episode begins with Ash, May, Brock, and Team Rocket traveling through a forest. They are in search of a new Pokémon to catch. As they walk, they come across a large pond where they notice a Whiscash swimming. Ash is excited about the possibility of catching a new Pokémon, and he decides to challenge it.

As Ash prepares to battle Whiscash, he sends out his Pikachu. However, Whiscash proves to be a formidable opponent, using its powerful Water-type moves to create waves that knock Pikachu back. Ash is determined to catch Whiscash, believing it will be a great addition to his team. He instructs Pikachu to use Thunderbolt, but Whiscash counters with its own Water Gun, creating a chaotic scene as water splashes everywhere.

Meanwhile, Team Rocket, who have been lurking nearby, see the battle and decide to intervene. They attempt to steal Whiscash for themselves, believing it will help them in their schemes. Jessie sends out Wobbuffet, while James uses Koffing to create a distraction. The chaos allows them to try and capture Whiscash, but their plan backfires when Whiscash uses its strength to shake them off.

Back in the battle, Ash continues to strategize. He realizes that Whiscash is not just a strong Pokémon but also has a unique ability to sense vibrations in the water. This gives Whiscash an advantage over Pikachu. Ash decides to switch tactics and calls back Pikachu, opting to use his newly evolved Treecko, now a Grovyle. He believes Grovyle's speed and agility will help him outmaneuver Whiscash.

As Grovyle enters the battle, it quickly showcases its speed, dodging Whiscash's attacks. Ash commands Grovyle to use Leaf Blade, which connects with Whiscash, causing significant damage. However, Whiscash retaliates with a powerful move called Earthquake, which sends shockwaves through the ground and knocks Grovyle off balance. Ash is worried but refuses to give up, knowing that he needs to find a way to outsmart Whiscash.

In a moment of inspiration, Ash remembers that Whiscash is vulnerable to Grass-type moves. He instructs Grovyle to use a combination of Quick Attack followed by Leaf Blade. Grovyle executes the plan perfectly, hitting Whiscash with a flurry of attacks. Just as it seems Ash might succeed, Whiscash uses its Water-type moves to create a massive wave, which overwhelms Grovyle and sends it crashing into the water.

Seeing Grovyle struggle, Ash feels a surge of determination. He recalls Grovyle and decides to use his last option: his trusty Charizard. Charizard flies in, and Ash commands it to use Flamethrower. The flames engulf Whiscash, and for a moment, it seems like Ash might finally catch it. However, Whiscash, using its resilience, manages to withstand the attack and retaliates with another Earthquake.

As the battle rages on, Team Rocket attempts to capture Whiscash again, but their efforts are thwarted when Whiscash uses its Water Gun to blast them away. This distraction gives Ash the opportunity he needs. He throws a Poké Ball at Whiscash, hoping to catch it. The ball shakes, and for a tense moment, it seems uncertain whether Ash will succeed.

Finally, the Poké Ball clicks shut, indicating that Ash has successfully caught Whiscash. He celebrates with his friends, feeling a sense of accomplishment. However, the victory is short-lived as Team Rocket, now furious, attempts to steal Whiscash from Ash. They launch a final attack, but Ash and his Pokémon work together to fend them off.
