Please help. I’m desperate

At my school (for the 15th time) we have a lil syncing contest, and my group made it through preforming navigating. There is a lot of money to win and the groups are VERY good. I was thinking about doing a backflip at one point or another, but I tried learning and didn’t get anywhere. Our team is falling off. We need people to help us out. If you have idea please dm me. It’s a HUGE thing at my school. I was lucky enough to make it past auditions. PLEASE! WE NEED SOME GREAT IDEAS
