Create dancing animation

I need just a simple animation done in the program of your choice (I'll just need a PNG sequence). The animation should be about 15-20 seconds long. The animation will be of the following: [login to view URL] - I need for these characters to be dancing, in whatever way possible. Just have them all dancing at the same time. This can involve hand or leg movement or jumping or whatever you think of. It should be just a quick animation, and I'll need the fully transparent PNG sequence after completion. I do not have the stick figures in large resolution, but I do have the smiley face in large resolution. If you need a larger resolution for the stick figures, you can probably draw it yourself. The resolution I'll need it in should be of width 500 and height 300.
