Coffins are recurring items in The Legend of Zelda series. They are usually found propped up against walls and occasionally on the ground. The coffins open up when Link gets close or shines light onto them. Usually containing an enemy such as a ReDead or a Stalfos, they can also hold items such as a Heart, Rupee, or Magic Jar.
Coffins are typically found containing Gibdos, Keese, or even a Small Key in a certain room at the Bottom of the Well. By lighting the torches next to these coffins in this certain room, Link can open the coffin. Whatever is inside will float or fly out, depending on whether it is a flock of Keese or a Gibdo.
Coffins can contain enemies such as ReDeads, Stalfos or Bubbles and items such as Hearts, Rupees and Magic Jars, or may contain nothing. If Link moves directly in front of one, it will fall on his head and damage him.
