This is the most difficult bottle to get. In order to get it, you need to ride
on Epona around Hyrule Field (day or night) and find 10 "big poes". You need at least one empty bottle handy. When you find a big poe, you have to shoot it twice with the fairy bow, when it falls hurry over and catch it in a bottle. Then bring it to the one eyed man in the gaurd house. The big poes
only appear in certain places. The map below shows where you need to ride to find each big poe.
Numbers on the map correspond to numbers below
