The Allay looks like a little blue fairy with bat wings. If you give it an item, it will pick up items of the same type abandoned nearby.
The Allay is the creature that won the Minecraft Live 2021 mob vote, over the Copper Golem and the Glare. It’s a mob that will be friendly to players and likes to dance to the sound of music blocks, it looks a bit like a baby Vex but much nicer. When he is given an item, he will search nearby to see if he can find similar items and then bring them back to the player. The Allay will always place the item it is carrying next to a music block if there is one nearby.
Note that the Allay will not duplicate the item he or she is carrying and will not search chests for it – he or she will only pick it up if it is on the ground.
