Notch created the first pig in the story of Minecraft. Yes, it was a happy day. But him, the master of all evil monsters, Herobrine, did not like it. He suffocated the pig until he gets an uncomfortable form (the form of a creeper) and then blew up the pig. But the pig did not explode. Because of the curse of Herobrine, the pig skin got rotten and absorbed the TNTs into his body. Creeper, the first monster was created. But he wasn't happy. Whenever a creeper try asking for help,the TNT explodes inside his body. So remember: the creeper doesn't explode because he hates you, but because he wants help.
