Pickle

Pickle 's are the power source to Mario or Luigi's fireballs. Just by destroying one of these sacred foods, the mario bros. could lose all their power. The pickle was mentioned first in Super Mario: The Cheese Adventure when Bowser complains about a sliver in his foot. He yells out with exclamination, "HOLLY PICKLESAUR MY PICKLING FOOT!" The pickle shattered into pieces in the game Yoshi's Island: The Battle For The Pickle, where all of the yoshi's teamed up to get the pickle pieces.
