Soul Bat

The soul bat is a variant of bat that is created when a bat is exposed to a soul based material or mob (warden, soul sand, etc.). The soul bat would be a passive mob that would drop randomized splash potions on player and mobs as they pass it by. The bat doesn’t defend itself when it is attacked and would fly away like a normal bat, however they are more comfortable around players and wouldn’t run away unprovoked. Soul bats could be both beneficial and harmful to players with these potion effects but finding a soul bat in a cave would also be an indication of the nearby dangerous warden. Adding the soul bat would open many doors in survival randomization and creativity with base design. Seeing as there are currently no craftable potions that are an instant kill for a full health player, the player would be safe from death by a soul bat by simply carrying a bucket of milk.
