When you get any power up it lets you run into a zapper and you survive but, you lose your power up whatever it is. What this power up dose is it lets you run into TWO zappers before you turn back into normal. So I guess you would call the power up Armour :)
Actually I was thinking about a rocket one. I guess that confirms it, A rocket power up! Hmmm.... maybe you could shoot the rockets at the zappers and stuff so they blow up so you don't run into them. :) thats an idea.
