A medium shot from a 3/4 view featuring a girl who is a personification of a watermelon, standing on a sunny tropical beach. She is a young woman with a curvaceous figure and large breasts, possessing vibrant green hair with dark stripes reminiscent of a watermelon rind and bright red eyes. She wears a sporty, form-fitting bikini made of a glossy red material with black seed-like patterns, paired with a translucent white sarong tied at her waist. She is holding a surfboard under her right arm, her left hand brushing a stray lock of hair from her face with a cheerful, beaming expression. The background consists of powdery white sand, crystal-clear turquoise ocean water with gentle waves, and a few distant palm trees under a brilliant blue sky. The lighting is bright and natural, with shimmering reflections on the water and a saturated, vivid color palette that emphasizes the contrast between the red and green of her theme, creating a refreshing and energetic summer atmosphere.
