whimsical storybook illustration: A hilarious action scene inside a boxing ring: a muscular black cat, wearing red boxing gloves and matching red boxing shorts, performs a dramatic flying kick mid-air, its long legs extended toward a giant T-Rex. The T-Rex, wearing blue boxing gloves and blue boxing shorts, leans back in exaggerated surprise, tiny arms raised defensively, mouth open in a comical yelp. Sweat drops and motion lines fly around them. The boxing ring has red ropes, a worn canvas floor, and bright overhead lights, with a cheering crowd of cartoon animals blurred in the background and a referee in black-and-white stripes crouching at the edge. Confetti and dust clouds add to the chaotic energy. Bright, vibrant comic-book colors — reds, blues, yellows — with bold outlines and exaggerated cartoon proportions. Funny, lighthearted, over-the-top sports action mood, like a Saturday-morning cartoon poster. No text.
