In this whimsical and humorous cartoon birthday scene, imagine a fantastical world where Warhammer Space Marines have swapped their battle gear for party hats and balloons. The setting is a vibrant alien planet, with swirling purple skies and crystalline formations protruding from the ground, adding an otherworldly charm. In the foreground, several Space Marines, each donning brightly colored party hats over their imposing helmets, are gathered around a colossal birthday cake shaped like a miniature fortress, complete with tiny turrets and battlements. The cake's icing is an iridescent blue, glistening like the hull of a starship.

Standing proudly at the center, a particularly charismatic Space Marine, holding a comically oversized slice of cake, raises his Power Fist in a jovial salute. The cake bears a bold inscription in whipped cream: "Happy Birthday Felix!" in an elaborate, futuristic font. Surrounding the cake, the Marines are engaged in lighthearted activities: one Marine uses a Chainsword to expertly carve more cake slices, while another inflates balloon animals shaped like tiny Space Marines with a small plasma-powered pump.

Behind them, a banner stretches across the scene, strung between two towering alien flora that resemble oversized, luminescent mushrooms. The banner reads, "For the Emperor... and Felix!" in vibrant red letters, a playful nod to their usual rallying cries. In the background, an alien creature with a comically large party hat of its own looks on with curiosity, holding a small gift wrapped in shimmering, metallic paper.

The sky above is an animated display, with stylized clouds that subtly form the letters of "FELIX" amidst twinkling stars, providing a cosmic backdrop to the celebrations. In a nod to classic cartoon styles, a few speech bubbles float above the Space Marines' heads, filled with phrases like "For the Birthday Emperor!" and "May your day be legendary, Felix!"

Overall, the scene is a delightful blend of sci-fi and celebration, capturing the essence of camaraderie and birthday cheer among intergalactic warriors.
