Big Poe

In Hyrule Field in the future, there are Big Poes rather than Stalchildren. This, larger and more aggressive version of the Poes hang out in specific parts of the Field and will attack you if you get close. They drop flames from their lanterns rather than hitting you directly and conventional weapons don't work against them. To defeat them, you have to ride at them with Epona and use the Fairy Bow to take them out. After that, you can collect them in bottles and bring them to the Poe Salesman at the entrance to the Hyrule Town Market. If you can bring him all ten, he'll give you an empty bottle as prize.
