Lantern

Hmmm... Well, let's see. What would a Lantern let you do? Summon Cuccos? Defeat Ganon? Perhaps shoot lava? Or maybe more unlikely, light a path? In most Zelda games, It is used to light a small area in dark places for Link to see. It can also be used to light stuff on fire. It will most likely have a use like that in TP, but who knows?
