In multi-player mode, how do you fly with someone holding on to you? It shows a pic in the instruction book, and I've seen a video of it on the Nintendo channel, but we have not been able to do it. I thought you just picked up the person that had the propeller hat, then they shook the remote, but it won't work! Please help. It's not really halting gameplay, we have beat it and have all 5 save stars, but it's driving me nutz!
