On the wario ware stage (all black except for chalkish drawings) be sure to do exactly as the commands tell you to do. for example, if it tells you to jump, jump quick so you don't get driven into the ground. If it tells you not to move, you could pretty much just let go of your wiimote. When it says pop it, it gets a bit confuzing, but just try to hit the thing that is most likely floating in the air. if you do the thing correctly, then it will give you a random powerup. if you don't do what it tells you to do, then nothing happens, but you may get killed if your opponent gets it and uses it against you.
