Imagine an endearing blend of childish delight and a rustic grunge style, where animated creatures are having a festive gathering. The various flocculent animals are adorned with playful badges imitating the emblem of a gritty rock band. They lift a toast with dark frothy beer mugs, bubbles fizzing over the rim. Overhead, countless tiny pieces of colored paper fall like a vibrant drizzle, intersecting with a garland inscribed 'Happy Birthday' against a pastel tinged heavens backdrop. Amidst this lively scene, a humorous multi-tiered cake draws attention. It is embellished with edible symbols of music and boasts an amusing imitation of a frothing beer mug as its crowning glory.
