In Happy Birthday you're in charge of serving the kids their birthday dessert. The desserts will be going across the screen in a conveyer belt and your job is to watch the bubbles over the kids' heads to see what they want and then click and drag the dessert over to the child. You'll start with only three desserts and the requests will be slow and easy to get used to, but as the levels progress so does the speed. There will be a lot more desserts to choose from, too. You'll have to be fast if you want to win Happy Birthday!
