Create a festive illustration that showcases a birthday scene. In the center, there should be a bright, cheerful bike decorated with vibrant party hats on the handlebars and a garland with vibrant colors wrapped around the frame. There should be an assembly of cartoon animals including joyful monkeys, happy rabbits, and excited elephants, all wearing party hats and blowing their noisemakers, surrounding the bike. In the background, a large 'Happy Birthday' sign should be prominently displayed. The sign is framed by a night sky filled with sparkling fireworks and twinkling stars.
