The newest addition to Minecraft, the hit indie game, and now for the new 1.21 update we will be seeing the armadillo and all its cool features such as the armadillo scute that you can use to craft armor for your wolf. It will implement a new feature of rolling up when a player gets close. This will be game-changing for the Redstone community, such as having a pressure plate or a calibrated sculk sensor activate when the armadillo rolls up into a ball. You can use it as a proximity mine with maximized lethality, including the armadillo, and using TNT minecarts you can have the trap be instant, and if you set up the whole area with TNT, the trap will be near unavoidable. And with the armadillo as the trigger, it will only be activated by a player, so you can be sure no normal mob will activate it.
