When a tiny and sad-looking Pokémon lands in Bonnie's hair, our heroes are determined to find out what's wrong! Its Trainer, Grey, explains that the little Flabébé has a special bond with his wife, Florence. She recently became ill, and when Flabébé tried to visit her in the hospital, a passing car blew its flower away. Without its flower, Flabébé is growing weak, but it won’t accept just any flower as a replacement—it needs a Fairy Flower, and those are hard to find!
Our heroes set out in search of the flower, "assisted" by Team Rocket disguised as tour guides. Bonnie spots a Fairy Flower growing high on the side of a cliff, and since Flabébé is too weak to fly, she climbs up after it as Ash, Serena, and Clemont watch anxiously from below.
While they’re distracted, Team Rocket nabs Pikachu! As a battle to reclaim it begins, Flabébé bonds with its new flower, and once its energy is restored, it floats over the villains and sprinkles them with its relaxing pollen. The Team Rocket members happily release Pikachu and wander off in a joyful daze!
Our heroes take Flabébé to meet Grey at the hospital. Florence perks up immediately upon seeing her dear friend. And though Bonnie has to say goodbye, her kindness and courage have saved the day!
As Ash and his friends prepare to set off again to the Shalour Gym, Bonnie encounters difficulties while fixing her hair. When Serena puts a flower clip in Bonnie's hair, a lone Flabébé attaches herself to it, looking downhearted. Bonnie feeds the Flabébé some nectar, and then asks Clemont if she can keep the Pokémon. When Clemont tries to capture her, however, the Flabébé refuses, and Ash points out she must already have a Trainer, angering Bonnie. The friends walk into the nearest town, Calanthe Town, to find her owner, with Bonnie still wanting to keep Flabébé for herself, talking to her in her hair by way of a mirror. Suddenly, an old man, spotting the Flabébé, runs up to the group, overjoyed. He introduces himself as Grey and thanks the group for taking care of his Pokémon. When he asks Flabébé to go home with him, however, she will not let go of Bonnie's hair. When asked about Flabébé's lack of a flower, Grey explains his story.
Flabébé lives together with Grey and his wife Florence. One day while gardening, Florence fell ill and collapsed. Flabébé, then with a flower, flew to find Grey. Florence was admitted to a hospital, where the old woman would stay. When Grey woke up the next morning, Flabébé was gone. On a hunch, he found Flabébé at the hospital, watching Florence. A strong wind separated Flabébé and her flower, and carried Flabébé away, while her flower was crushed by a passing car. Now Grey must take Flabébé back quickly, as Florence is not doing well, due to an emotional matter. As long as Flabébé remains flowerless, she will continue to lose her energy. The group suggests they pay a visit the florist, but Grey reveals that every Flabébé chooses their favorite flower from birth. He admits finding the right fairy flower will be a hard task. Ash and the others tell Grey to go visit Florence while they go search for the flower.
The group first goes to a Pokémon Center to heal Flabébé, where Nurse Joy tells them that fairy flowers may be found in the high plains near the town, but they are not in season. Team Rocket watches from behind newspapers and hatches a plan. As Bonnie and the group are about to head out, a disguised Team Rocket stops them, offering a special tour to find the fairy flowers. The "tour guides" escort the group quickly to the high plains, where the group begins to look for a flower. Flabébé spots one high on the side of a cliff, which Bonnie must climb because Flabébé must attach herself naturally to the flower. Meowth encapsulates Pikachu with a claw as Bonnie and Flabébé reach the flower. Ash, Clemont, and Serena call out Froakie, Chespin, and Fennekin, while Jessie and James retaliate with Pumpkaboo and Inkay. Ash commands Froakie to use Water Pulse, but the move is reflected by Wobbuffet's Mirror Coat. Chespin uses Pin Missile, but it is also reflected, hurting Ash, Clemont, and Serena's Pokémon. James and Jessie order Inkay and Pumpkaboo to use Psybeam and Shadow Ball on the opposing Pokémon, who are unable to retaliate. Just then, Flabébé, now on her new flower, flies over the battlefield, using its pollen to subdue Team Rocket and their Pokémon. Under the calming effects of Flabébé's pollen, Team Rocket releases Pikachu on their own accord. With Team Rocket out of the way, Flabébé and the group return to town to find Grey.
The friends arrive at the hospital, and Florence and Flabébé are reunited, giving the old woman hope. Grey and Florence thank Bonnie, and Bonnie and Flabébé share a heartfelt goodbye. Coming out of the hospital, Bonnie is upset about having to leave Flabébé, but Dedenne cheers her up with a gentle nuzzle. With that, Bonnie joins her brother and the others as they continue onto Shalour City.
