Minecraft After All

    It's a world of pigs and a world of sheep
    It's a world of zombies, a world of creep
    ers that blow up your head
    as they kill you so dead
    It's a Mine... craft... world!

    It's a world where water is made in blocks
    It has trees on clouds, it has floating rocks
    It's a world where we build
    And respawn when we're killed
    It's a Mine... craft... world!
