In a lively birthday setting, the illustration enchants with a charming retro gaming theme. A generic fast-paced blue creature, akin to an anthropomorphic hedgehog, becomes the primary focus, equipped with a party hat, ardently playing a rock guitar amidst vintage game cartridge and console decor. The scene is invigorated by a symphony of notes symbolizing rock music, while various elements like pixel art style party banners and a 'Happy Birthday' inscription in conventional arcade typography enrich the backdrop, paying tribute to the golden era of gaming.

Generated with these themes: Retro gaming, Sega, Sonic the hedgehog, and Rock music.
