Feed it food. Watch it grow. Watch as it destroys everything in its tracks. Famous cities are smooshed in mere milliseconds, as people try to run but get caught in this dry, rocky, fire. The scratch HQ is crumbled instantly and games stop working. It doesn't matter, though. There are NO computers anymore. The Earth starts to crumble under the weight of this chunky boi. Eventually, it can't sustain it any longer, and, just like everything else, gets smooshed by this rock. Except it's in space, so it doesn't really get smooshed. It becomes larger than Earth, then, Uranus, Neptune, Saturn, and Jupiter. It destroys the sun and causes a super nova, yet the black hole inside can't eat this ginormous man. It eventually dies out as well due to Hawking radiation, causing a huge explosion that destroys the Oort Cloud, but not this monstrosity. It expands to the size of our galaxy, our cluster, our supercluster, the ENTIRE observable universe. It eventually reaches the end of the universe and pushes out on the universe, causing it to explode. This monstrosity eventually becomes our universe inside, because of the amount of mass near the core causing something similar to the Big Bang. The universe stuff going on slowly eats this creature from inside out, as it struggles to keep up with it, even eating more food faster. But the universe inside expands faster too. This "pet rock" knows it will die once the universe inside of it starts to go faster than the speed of light, which is already happening... who will win, the rock or the fledgling universe?
Should I work on the story more, maybe in a part 2? Probably not since this is a joke, but if you guys really want it, ask in the comments and give a love and favorite, please! Also, follow @CodePuff if you think this project deserves a follow. Also, if you couldn't tell already, I'm not the best writer in the world.
