Shulkers are unique hostile mobs found in the game Minecraft. They are primarily located in End Cities, which are structures that players can explore after defeating the Ender Dragon. Shulkers have a distinct shell-like appearance and can blend in with their surroundings, making them difficult to spot. When attacked, Shulkers shoot projectiles that inflict a status effect called "Levitation," causing players to float upwards. This ability can be both a challenge and an opportunity, as players can use it to reach higher areas. Defeating Shulkers rewards players with Shulker Shells, which can be used to craft Shulker Boxes for inventory management.
