At the top of the Cartoon Style image, Happy 11th Birthday!

A big, funny, high-energy cartoon scene starring Sonic the Hedgehog, Knuckles, Tails, and Amy in a Green Hill Zone-inspired party: bright checkerboard hills, loop-de-loops, palm trees, and a sky of fluffy clouds. Sonic, huge grin and exaggerated sneakers, blazes as a blue blur through a giant loop shaped like the number 11, balancing a gleaming golden-ring birthday cake; iced on the cake in chunky frosting, small text: Gotta go 11! Tails hovers with his twin tails spinning like rotors, piloting a tiny party drone that trails streamers and ring-shaped balloons. Knuckles, party hat askew, uppercuts a ring piñata, bursting it into a shower of glittering gold rings, candy, and confetti. Amy Rose, beaming, mid-swing with her oversized hammer to pop a massive ring balloon into starry sparkles, holding a gift with a heart sticker.

Style and mood: playful cartoon with exaggerated proportions, thick black outlines, bright saturated colors, and whimsical, energetic poses; comic-book flair with halftone dots, bold speed lines, and swoosh arcs; glossy highlights on rings and cake; wide-angle, low-perspective composition that feels full-bleed, fast, and funny.
