Waku, an adorable turtle with vibrant green skin and a rich brown shell

Waku, an adorable turtle with vibrant green skin and a rich brown shell, looks up with bright blue eyes shining with excitement, as if celebrating a triumphant spike, stands on a modern volleyball court covered with polished wooden floors, holding a volleyball in her hand, wearing a tank top with a stylized orange lowercase "W" logo on the chest, her tiny tennis shoes laced up and ready for the next serve, capturing the essence of her spirit cheerful and competitive, with soft, warm lighting that casts a comforting glow on the overall scene.
