These are really fun to fight! It also helps to have some fairies on you in case you can't escape the ice, the fairies can be found in the Sky Islands (or Great Fairy Fountains) Also, any bows like the Great Eagle Bow that can release multiple arrows at once help too. The eyeballs will split into three (for the Great Eagle Bow) and they usually hit all the heads at the same time. (Sorry for writing so much)
