High quality, high detail, a masterpiece. A pond overgrown with duckweed, with dark but clear water visible in places. A close-up of a greenish-brown frog perched on a lily pad. A small golden crown is on its head. In a column of golden light, the frog completely transforms into a slender, beautiful, naked human princess with long, ash-blond hair, a sweet feminine face, and feminine arms, legs, and body. She becomes a 100% female figure, her legs up to her knees submerged in water.
