They come at me, then I point to the Germans next door.
A creeper set on power lvl 100 is now chasing you. (It is set to blow within 1 second of reaching target range, has Wither armor [no arrows], and will detonate anything within a 200 block radius if it blows.) Yes, this is possible in vanilla. My brother enjoys spawning them near me with command blocks in single-player LAN.
