Copyright Valiant Technology Ltd Cave Rescue? Trog is an eccentric Roamer. While most robots liked sunning themselves on the beach, he liked crawling into the deepest, darkest caves. One day he was exploring Magnetometer Pothole when he found some new passages. He knew he was the first robot to ever trundle through these splendid caverns: wow did his circuits buzz! In fact they buzzed so much he forgot the time. He was busy exploring what he later named “Justanastypassage” when his light went out. “Oops” There was nothing for it – he had to feel is way out of the cave.
