pretty hard to decide since i hate almost any mob that gets in my way.
-Creepers, they blow up and make these ugly potholes and i have to cover them up, sneaky buggers also sometimes get inside the house and blow almost half the thing to smithereens.
-Zombies, you know when you hit one zombie, it spawns in two more zombies for reinforcement? yeah have a zombie swarm and each zombie is allowed to call in two more, then you have to deal with the frickin zombie apocalypse.
-Phantoms, i don't sleep. that's not my fault as i play on a server where it's impossible to sleep, and i tend to build tall structures.
-Cave Spider, one bite and i'm as good as dead.
-Enderman [Bedrock Edition] you don't even look at them, they get mad at you.
-Ghast, it's a flying sniper cannon that makes abysmal sounds so loud you can hear it a hundred blocks away.
-Bat, no explanations needed
-Pillager [Bedrock Edition] these guys got machine guns or something? they reload too quickly.
