Mobs

 * Allay

 * It can be made to hold an item by interacting with the allay (pressing ).
 * The item can also be removed by interacting with the allay (pressing ) while with an empty hand.
 * Able to drop items at nearby note blocks, and stay close to a note block that has been played near them.
 * When playing a note block near them, that note block becomes their favorite one for 30 seconds, and they will attempt to drop off items at the note block rather than at the player.
 * If they have items in their inventory, they will attempt to give them to their owner.
 * Sometimes spawn in cages next to pillager outposts (similar to iron golem), and inside woodland mansions.
 * Has a delay for picking new items after delivering items.
 * Immune to damage from its owner while holding an item.
 * Have health points.

 * Contains chests with unique loot, like the swift sneak enchantment.
 * Other valuable loot includes the Otherside music disc, Potions of Regeneration II, enchanted books, enchanted iron and diamond leggings, enchanted diamond hoes, and enchanted golden apples.
 * If the frame of reinforced deepslate generates with a chest in front, it will always contain one golden carrot (a hint about how to open the secret door below).
 * Has different levels and open spaces, with several types of ruins and wall structures.
 * Some of these structures contain dark oak logs, planks, and fences; cyan, light blue, and blue wool and carpets; ladders; ice and its variants; note blocks; stone pressure plates; and iron trapdoors opened with levers.
 * Hidden underneath the frame of reinforced deepslate are several rooms containing redstone mechanisms that serve to introduce new players to their function.
 * Each variant of the city center has a different redstone puzzle concealing the entrance, requiring slightly different strategies to solve.
 * The mechanisms are made with redstone dust, redstome torches, redstone repeaters, redstone comparators, redstone lamps, blocks of redstone, sticky pistons, a sculk sensor, a target, and a lectern.
