Ender pearls are special items in the game Minecraft that players can obtain by defeating Endermen. When thrown, they allow players to teleport to the location where the pearl lands, making them useful for navigating the game world quickly. In addition to their teleportation ability, ender pearls are also essential for accessing the End dimension. Players need to collect them to craft Eye of Ender, which is used to activate the End Portal and ultimately face the Ender Dragon.
