An ender pearl cursor! It's an item used to teleport and to make the eye of ender. It is a rare item, which drops from an Enderman. An eye of ender is a craftable item used to locate strongholds and activate the end portals within them. Once an end portal is found, the eyes of ender are required to activate it. End portals require a total of 12 eyes of ender in order to activate, though each individual frame-block has a 10% chance of containing an eye of ender when generated.
