A melancholy penguin wearing a bright pink sombrero and oversized novelty sunglasses, sitting on a giant inflatable unicorn floatie in the middle of a vibrant, turquoise ocean, surrounded by a swarm of rainbow-colored seagulls, all set against a bright, radial gradient background that shifts from citrusy orange to lemony yellow, reminiscent of a sunset on a tropical island, with cinematic lighting and 3D shading inspired by the likes of Pixar, Disney, and Industrial Light and Magic, with intricate details and textures akin to concept art created in Maya 3D and ZBrush, all rendered in stunning 4k resolution with meticulous post-processing to create a humorous and eye-catching image.
