a detailed and playful line drawing featuring a cartoon-style cat.

In this whimsical scene, a cartoon-style cat with oversized paws and a mischievous grin sits on a sun-kissed beach, diligently crafting an elaborate sandcastle adorned with spiraling turrets and grand archways, all while a gentle ocean breeze ruffles its fur. Nearby, a colorful bucket and shovel lie ready for the next scoop of sand, accompanied by a curious starfish and a sparkling seashell that reflects the playful spirit of the seaside.
