Tsurube-otoshi

It's a spooky-looking, big-headed monster that suddenly appears in the dark forest. When this mob finds a player, villager, Illager, or Wandering Trader, it jumps and attacks like a slime or magma cube. The time of appearance is mainly midnight, and it appears suddenly. Appearing suddenly can scare players like creepers and wardens. If you have any other good ideas, let us know in the comments. Thank you for taking a look at my thoughts.
