Buổi tham quan thủy cung phong cách anime vào Ngày cá chình vườn

Polished anime-style vertical illustration set inside a modern public aquarium on the morning of [11月11日]. Exactly two main characters stand in front of a huge curved glass tank filled with deep blue water, rocky reef formations, bright caustic sunlight reflections, tiny fish silhouettes, and exactly 16 visible spotted garden eels emerging from the sandy bottom. Left character ([Muumuu Bell]): tall, gentle cow-girl with very long pale lavender-white hair ending in turquoise tips, small tan cow horns, cow ears, golden-brown eyes, and a soft curious smile with one finger near her mouth. She wears a large gold cowbell at her neck, a sleeveless white cow-print top, pale shorts with blue trim, white thigh-high cow-print stockings, an oversized black jacket slipping off her shoulders, and a thin cow tail with a black tuft. Right character: shorter adventurous cat- or wolf-eared boy with sandy blond hair, amber eyes, animal ears, a fluffy brown tail, dark brown expedition coat, red scarf, black gloves, utility belts, pouches, backpack, small tools, and a long rifle-like prop strapped to his pack, pointing excitedly toward the garden eels. Text and graphic elements: - Upper left: a warm glowing rounded-corner sign with Japanese text: large title "[穴子の日]", smaller top date "[11月11日]", a simple eel icon, and a small Japanese subtitle meaning "rediscover the charm of garden eels." - Bottom right: handwritten white Japanese greeting "[おはよう]" with a small sun doodle on the aquarium floor or glass. Cinematic vertical composition, soft rim lighting from the tank, deep blue ambience, warm sign glow, expressive faces, detailed clothing accessories. No extra characters, no watermarks.
