Imagine a bustling gym setting, alive with the charm of classic cartoon exuberance. At the center, three whimsical cats are depicted with exaggerated, playful features that highlight their athletic endeavors.

The first cat, an orange tabby with a sleek yet comically oversized head, is wearing a tiny black headband and lifting exaggeratedly large dumbbells that are humorously lightened with visible "puff" air lines above its head. Its eyes are wide, showcasing determination. The dumbbells themselves are black with orange accents, in line with the card's thematic colors.

Next, a black and white tuxedo cat with a mischievous grin and big round eyes is mid-jump on a trampoline. The trampoline's springs are exaggeratedly stretched, conveying a sense of lighthearted action. This cat wears orange wristbands and sports a small, cartoonish sweat droplet on its brow.

The third feline, a petite orange kitten, is energetically skipping rope. The rope creates dynamic, looped shapes around it. It wears oversized black sneakers that add a humorous touch to its small stature.

The gym background is vibrant with cartoonish details: a row of black and orange striped yoga mats, and an oversized wall clock with cartoonishly large numbers and hands. The walls are splashed with an abstract orange pattern, reminiscent of a comic panel backdrop.

Scattered throughout are small, exaggerated gym equipment pieces, like a lopsided water bottle and an oversized towel, adding to the overall playful scene. The floor is a checkerboard of black and orange tiles, grounding the illustration in its vibrant color theme.

Above the cats, in bold, playful cartoon letters, the word "CONGRATULATIONS!" arches across the scene, adorned with tiny, jubilant stars and confetti-like accents, amplifying the celebratory feel of the cover.
