“Rexy? Who’s Rexy?” I asked. I was answered by a large creature as it broke through the treeline behind us, releasing a deafening roar as it did so. It was massive, at least thirty feet long from head to tail by my estimate. Two powerful legs powered the creature's locomotion, while two small arms sat almost uselessly in front of it. Top it all off with its mouth filled with rows and rows of sharp banana sized teeth and scaly skin, and you had the makings of a monster straight out of a foal's nightmares.
