Moop, a moon spirit born of the Fountain of Sky, drifts with a legless, verdant body adorned by large rounded ears and luminous emerald eyes. A crimson orb glows at his tail’s tip, while a golden sphere etched with a delicate heart marks his forehead. His speech lilts with "-mupu," a whimsical suffix echoing his lunar origins. He channels celestial energy through allies like Flappy, unlocking transformations such as Cure Bright. Teaming with Foop, a spirited wind companion, he summons mystical accessories to enhance the Pretty Cure’s prowess. Their curious wanderings, though well-meaning, often spiral into unforeseen chaos. Moop’s bond with Foop thrives on unwavering trust, a camaraderie cemented when the Kiryuu sisters, Michiru and Kaoru, saved them from a falling tree at the Fountain. This rescue kindled Moop’s enduring loyalty to Michiru, whom he reveres as a guardian of boundless compassion. Amid battles against adversaries like Fusion, Moop relies on protectors like Shiny Luminous while fueling the Pretty Cure’s united assaults. He amplifies their power through the Rainbow Miracle Lights, intertwining his magic with theirs. Though mischievous, his shy nature belies a steadfast devotion to safeguarding those he holds dear.
