At the top of the image, "Mark, prepare for puckin' glory and battle biscuits — it's your Warbarkday!"

- In the center of the image, illustrate a hilarious battlefield-ice-rink hybrid where armoured Space Marines are clashing mid-ice hockey match against a squad of armored Border Collies, each one wearing Warhammer-style shoulder pads and visors.

- One particularly smug Border Collie (wearing goalie gear) is dramatically blocking a slapshot using a glowing power paw.

- Mark is represented as a heroic Warhammer commander riding a rocket-powered Zamboni, wielding a hockey stick like a mighty staff, cape billowing, with birthday candles lighting the tip of the stick.

- Exploding birthday cakes serve as landmines on the ice, and there's a referee servo-skull hovering nearby blowing a party horn.

- Make the color palette epic but silly — bright armor, rainbow confetti flying through the air, and an occasional rubber chicken wedged between hockey gear.

Generated with these themes: Warhammer, Ice Hockey, and Border collies.
