New Super Mario Bros. Tips

Easy Lives
To get really easy one ups, go to level 1-1. Bump the mega mushroom box, and then let it travel all the way right until it's at the edge of the cliff. Grab it, then run through the level, destroying everything. If you did it right, you can smash over the flag jumping stairs and even the flagpole and get lots of one ups. Best of all, you can do it over and over again!
