a heartwarming scene in the style of a detailed cartoon line drawing, meant for coloring.

In this whimsical line drawing, a cheerful elephant, with oversized ears fluttering in the sea breeze, is joyfully constructing an elaborate sandcastle, diligently scooping up mounds of sand with its playful trunk. Scattered nearby are a colorful bucket and spade, while the serene horizon stretches out with soft waves lapping against the shore, creating an idyllic backdrop for this delightful beach scene.
