It was a week after all the kids became animals when the aliens came (to everyone's surprise). The invasion started with a worldwide flash that caused all technology to fry making it worthless. When the aliens landed everyone was quite surprised to see they looked much like earth animals but anthro forms of them. The aliens landed in force and started killing every adult on the planet. In 3 weeks the human race was no more. Without the technology to turn animals into humans the human race could never be restored. The aliens decided to stay on Earth and live here since they liked what they saw. They treated all the kids turned animals really well. No one ever figured out how they seemed to know the plan. The End
