This command gives you a spawn egg of a creeper that can be your pet. This is only 2.0 so there will be improvements. If the creeper explodes it will only take out 4 blocks, unless those 4 blocks are diamond, then there is no reason to get upset. If you kill the creeper then you will get 5 random chance ores, Coal, Gold, Iron, and Diamond This command doesn't work in the chat it only works in command blocks. So with that, have fun!
