I rewrote this story. Also, it's human forms.
When the Ender Dragon, King of the End, create the mobs, creepers, pigs, and etc, he left out three species. The Thunder-Shockers, Night Shaders, and the Ashanders. He thought they weren't ready to be out there yet. So few years after that, the Ender King finally let them in the overworld. Now the mobs there doesn't know them, except the enderman. So the new mobs are new to them. Three girls, one from each species, meet some mobs in the overworld, gaining friendships and maybe more. What will happen when they encounter the mobs in the overworld? Read to find out.
