Beneath a sky sprinkled with cheerful, fluffy clouds, a whimsical cartoon elephant joyfully stacks sand into a grand sandcastle, its trunk playfully shaking grains as gentle waves tickle the shore nearby. Scattered around the sandy scene, an array of colorful seashells twinkles in the sunlight, while a curious seagull stands guard, eyeing a vibrant beach towel and bucket poised near the elephant’s sandy masterpiece.
