When the Caribou came and took over Equestria, they caught Celestia trying to mess around some type of control panel. Feeling she was sending a distress signal to one of Equestria's allies, they destroyed the panel. But in doing so, they released something from the darkest part of the Everfree Forest. And now the creatures are free to do what they want with the Caribou. All hail the dinosaurs... LONG... LIVE... JURASSIC EVERFREE!
