Flappy is a flower spirit who enables Hyuuga Saki's transformation into Cure Bloom and later facilitates her additional power as Cure Bright using Moop's lunar energy. His appearance features a pale blue-white body accented with sky blue markings, black eyes that frequently appear dark red, and a tail culminating in a distinct flower shape. Petal-like features frame his eyes, a flower bud motif adorns his forehead, and he wears a red-to-pink necklace centered with a golden yellow orb. His name combines "flower" with a descriptor for something light or waving in the wind. Personality-wise, Flappy demonstrates responsibility and leadership, readily taking charge and expressing opinions directly. He exhibits determination in pursuing goals and protecting loved ones, consistently supporting Saki despite occasional disagreements. A notable aspect involves romantic feelings for Choppy, which trigger shyness, defensiveness, or exaggerated reactions when confronted, though he consistently shows her subtle affection. Flappy first appears with Choppy as balls of light approaching Saki and Mishou Mai at the Sky Tree, reminding them of a past encounter and urging them to become Pretty Cure defenders. After their initial defeat by Karehan, Saki defends Flappy, catalyzing her transformation into Cure Bloom. He resides with Saki, sharing a generally positive rapport despite periodic arguments, such as when Saki mistakenly blamed him for oversleeping due to a displaced clock, later discovering he was actually ill. During this incident, he developed a fever; after Saki rescued him from drowning following a Moerumba attack, he reciprocated her care when she caught a cold. His romantic subplot develops when a movie-inspired reenactment leads to a failed confession attempt toward Choppy, interrupted by her distraction with a butterfly. This drew teasing from Moop and Foop, causing Flappy to snap at them before reconciling. A significant turning point occurs when Goyan captures Flappy and Choppy through a dimensional portal to locate the Fountain of Sun. Additional traits include a preference for rice-based foods and a physical reaction where his ears straighten when frightened. His emotional vulnerability surfaces around discussions of his crush.
