Jim Passmore was enjoying a quiet walk around Haikey Creek, Oklahoma, when he stumbled across a rather distressing sight. There, stuck in the water, was a giant animal struggling to free itself from the mud. Passmore looked closely at the tired, feathery beast – and concluded that it was an over-sized beaver. But even if he couldn’t be sure of what animal he’d found, one thing was clear: there was no time to lose if he was going to save its life. After Passmore leaped into action, though, he was in for a shock when he finally saw the animal’s face.
