New Super Mario Bros. Wii Tips

Protect Your Head!
If you are on a level like 8-5 or 7-Fortress you will know that bomb-ombs and other enemies rain on you from above. If you freeze an enemy and hold it above your head, when another enemy "rains" on you it will hit the frozen enemy and break it instead, leaving you unharmed. You can do this with unfrozen Koopas, but they may come out of their shells harming you while you are holding them.
