At the top of the Cartoon Style image, Happy 8th Birthday Arthur

Playful, bright cartoon scene with exaggerated proportions, thick black outlines, and energetic poses. A giant black-and-white chessboard has become a lively birthday party floor. Center stage: Arthur, a joyful cartoon kid with big expressive eyes, a shiny gold king’s crown, and a red cape, rides a goofy grinning knight chess piece like a bouncing hobby horse, one hand in the air, the other clutching a party horn. The knight has a toothy smile and oversized hooves, mid-gallop with motion swooshes.

On the center square sits a towering cake decorated like a chessboard, icing dripping, sprinkles shaped like tiny pawns and rooks, and a glowing number 8 candle on top. Around them, anthropomorphic chess pieces celebrate: a sassy Queen with sparkles striking a pose, a Rook firing confetti from its turret, Pawns in party hats carrying cupcakes, a Bishop tooting a party blower, and a King tipping a polka-dot party hat.

Festive balloons shaped like chess pieces float overhead; colorful bunting stretches between tall rooks. Add streamers, confetti bursts, sparkles, and dynamic action lines for a fun, chaotic party feel. Use a vibrant palette (electric blues, cherry reds, sunny yellows, lime greens, royal purples), bold thick outlines, soft cel shading, and a slight fisheye perspective for extra whimsy.

Style the header text in big bubbly letters across a checkered banner held by two smiling rooks in party hats.

Include one small, funny text element: a speech bubble from the knight that says: Have a KNIGHT to remember!

Clean, crisp finish; no extra text beyond the header and the speech bubble.
