User SargeantJared found an amazing little hidden feature.
Explosive Sheep
Hello there, SargeantJared here!
Today I have for you explosive sheep
to use in adventure maps or troll/prank
your friends.
What is it?
These are explosive sheep. They seem friendly, but
when you get too close they explode. Remember to be
careful when using this as it does blow up/damage blocks.
Tutorial:
Simply type this where you want the explosive sheep to spawn:
/summon Creeper ~ ~ ~ {ActiveEffects:[{Id:14,Duration:999999,Ambient:1}],Riding:{id:Sheep}}
How does it work?
The command spawns a sheep with an invisible creeper on it.
Enjoy
