Ash, Misty, and Brock are traveling through the Johto region when they come across a Pokémon Center. Inside, they meet Nurse Joy, who is busy tending to a Dunsparce that has been injured. The Dunsparce is a rare Pokémon, and Nurse Joy explains that it has been causing trouble in the area, leading to a series of misunderstandings about its behavior. Ash and his friends express curiosity about the Dunsparce and decide to help.

As they leave the Pokémon Center, they encounter a group of trainers who are discussing the Dunsparce. One trainer, named Kenta, is particularly interested in capturing it. He believes that the Dunsparce is a powerful Pokémon and wants to add it to his team. Ash, Misty, and Brock overhear this conversation and become concerned about Kenta's intentions, fearing that he might not treat the Dunsparce well.

The group decides to investigate the situation further. They head into the nearby forest where the Dunsparce was last seen. As they search, they come across various wild Pokémon and experience some lighthearted moments, showcasing their camaraderie. However, their search takes a serious turn when they finally spot the Dunsparce hiding in a tree. It appears frightened and wary of the trainers.

Ash approaches the Dunsparce slowly, trying to gain its trust. He kneels down and offers it some food, but the Dunsparce remains hesitant. Meanwhile, Kenta arrives on the scene, determined to catch the Dunsparce. He throws a Poké Ball, but the Dunsparce dodges the attack and escapes into the bushes. This prompts a chase, with Ash and his friends trying to protect the Dunsparce from Kenta.

During the chase, Ash sends out his Pokémon to help corner the Dunsparce safely. Pikachu and others work together to guide the Dunsparce away from Kenta.

Eventually, Ash and his friends manage to create a safe space for the Dunsparce. They explain to it that they mean no harm and that they want to help. The Dunsparce begins to trust them, and they form a bond. Just as they are about to celebrate their success, Kenta reappears, furious that he has lost the Dunsparce.
