Just in cast people find this as a spoiler I will put this after the break.

In their preview Joystiq has some interesting information.

“If you lose five lives on any given level, the game will give you an invincible Tanooki suit — think of it as having constant Star power while wearing the Tanooki suit. You can still fall to your death, so if you die ten times on a level, a special P Wing block emerges, allowing you to zip right to the end.”
