A vibrant, jovial scene of an imaginative themed birthday celebration, filled with cartoon-like alien creatures wearing festive hats and playing instruments. Instead of famous characters, have a green, small alien with pointed ears; a tall, dark-costumed figure with a helmet; and a big furry brown co-creature. Include animated human band members with distinctive hairstyles, no relation to any famous bands. Above them, a 'Happy Birthday!' banner in bold letters. Small furry creatures and unique bird-like species frolic around a cake fashioned like an eccentric underwater vessel, with futuristic sword-shaped candles adorning the top.

Generated with these themes: Star wars, and The Beatles.
