Didonian arthropod

On Dido, Ian Chesterton, Barbara Wright and Vicki Pallister hid from an arthropod. It was massive, with a slimy, featureless face with red eyes and a thick, segmented body. When it emerged from the ground, it left debris as a sort of plug. As a result, it unearthed a number of bones belonging to animals and Didoi. (PROSE: The Rescue)
