Create a vibrant birthday party backdrop featuring a colorful balloon arch in shades of pink, blue, and yellow, surrounded by a cascade of confetti raining down. In the foreground, include a large, tiered birthday cake adorned with colorful frosting and candles, along with wrapped presents in festive paper. The scene should be set in a cheerful outdoor garden with string lights overhead and a banner that reads Happy Birthday! hanging between two trees. Add playful elements like party hats, whistles, and a whimsical cake topper of cartoon animals celebrating together.
