The ground trembles. The trees shake. The Porkosaurus Rex stands three stories tall with a mouth big enough for you to run thru. The huge head comes straight down at you. Its large beady button eyes are fixed on you. You leap into the air, grab a low hanging branch and swing yourself up. The Porkosaurus crunches into the ground where you were. As he lumbers up into a sitting position you stand and bounce on the branch you're on and launch yourself into the air over his head. You catch a higher branch and find yourself swinging directly over his head.
