Catchy little melody sound (2-3 seconds)

Hi, I need somebody to create a nice little catchy sound that would last about 2-3 seconds. One example of such thing is when you enter Skype, you hear the Skype's startup sound. I need something similar for a video chatting website. Perhaps you can use some kind of water bubbly sound, or any little melody that comes to your mind. Thank you Note : Please provide some sample and the best will be chosen...
