The scene unfolds in a whimsical, vibrant town square on an alien planet that blends classic Earthly charm with cosmic eccentricities. In the center, a lively birthday parade marches through, led by a stout, jolly skinhead whose head shines under the twin suns, humorously clad in a homemade Darth Vader helmet crafted from papier-mâché. He's riding a gleaming Lambretta scooter that defies gravity, floating effortlessly a few inches above the cobblestone streets. The scooter, adorned with checkerboard decals and ska-themed insignia, hums with an otherworldly tune, a mix of ska beats and intergalactic rhythms, playing from its retro-futuristic speakers.

On the scooter's rear, a vintage amplifier is strapped, broadcasting "Happy Birthday, Grum" in bold, colorful sound waves that ripple through the air, creating a vibrant banner above the scene. As the parade progresses, a group of cartoonishly rendered stormtroopers, with mod parkas over their armor, play trumpets and trombones, belting out ska riffs with exaggerated, joyful expressions.

In the background, various alien creatures, inspired by the playful exaggerations of Hergé and the comic dynamism of Bill Watterson, dance and skank along the sidelines. They hold up signs with cheeky messages like "May the Ska be with You!" and "Keep Calm and Ride On, Grum!" The sky, an amalgam of hues from a setting alien sun, features clouds that whimsically form the letters of "GRUM" in puffy, bold fonts reminiscent of classic comic book styling.

Nearby, a colossal birthday cake towers in the shape of the Death Star, but with a cheeky twist: it's adorned with ska checkerboards and topped with sparklers shaped like tiny Lambrettas. Around the base, smaller cakes spell out "Happy Birthday Grum!" in icing that gleams like the stars above. It's a delightful, jubilant scene packed with lively detail and comic charm, ready to leap off the card into Grum's imagination.
