Ash, Serena, and Clemont are traveling through the Kalos region when they arrive at a large lake. The group is excited to take a break and enjoy the scenery. As they approach the water, they notice a group of Froakie playing near the shore. Ash is particularly interested in the Froakie, as he has a fondness for Water-type Pokémon. The atmosphere is light-hearted, and the friends share a moment of laughter as they watch the Froakie splash around.

Suddenly, a commotion breaks out as a group of Team Rocket members, consisting of Jessie, James, and Meowth, appear on the scene. They are scheming to capture the Froakie and other Water-type Pokémon in the area. Team Rocket sets up a trap using a large net, intending to ensnare the Froakie and any other Pokémon that come near the water. Ash and his friends quickly realize what is happening and spring into action to protect the Froakie.

Ash sends out his Pikachu to confront Team Rocket. Pikachu uses Thunderbolt to disrupt their trap, causing the net to malfunction. Team Rocket, frustrated by their failed plan, decides to engage in a battle with Ash and his friends. Jessie sends out her Wobbuffet, while James uses his Weezing. The battle intensifies as Ash commands Pikachu to attack, and Clemont sends out his Bunnelby to assist. Serena, meanwhile, is focused on keeping the Froakie safe and away from the chaos.

As the battle rages on, Team Rocket attempts to regroup and launch another attack. They use a combination of Wobbuffet's Counter and Weezing's Smokescreen to create confusion. However, Ash and his friends work together, coordinating their attacks to counter Team Rocket's moves.
