Seemingly Impossible Heart Piece
You know the cage in Impa's house with a cow and Heart Piece inside? It is actually possible to get it. Go to the top of the watchtower thing in Kakariko, and then Longshot to the blue roof where you find the man who gives you a Heart Piece(get that one if you dont have it already) then longshot to a space inside the windmill where an opening is with a light brown object inside. longshot to it. Then go up the staircase where you find a chicken. grab it, and fly over to the area above the place where you find the cucco lady with the logs below it. go in, and you find a Heart Piece.
