find a small group (or go solo) and just make a cute idol costume and re-create a dance and/or sing. there are probably videos of the previous years around here somewhere. It's really up to you to do anything you want. scoring seems to be based on how creative and how much you did yourself vs. how much is pre-recorded, lipsynced etc. and not so much about actual skill. but it's all for fun in the end, no actual talent required.
