Silver beetles are creatures that were originally from another galaxy but managed to find a way to step from their chain of worlds to Earth West 1,217,756.
They had a human-sized face, that was insectile and shining black, with a multiple eye. Half of it was coated with a silvery metal, a mask.
They were first encountered in 2036 by Cassie Poulson while she was digging a cellar outside her house in New Springfield on Earth West 1,217,756 but she quickly refilled the hold and never told anyone about it.
