Creepers are large ground cover plants, clusters of vines that create a lattice or net. The central pod puts out 12 to 50 runners (vines that can root and continue on). Each creeper can cover about a twelve foot (3m) diameter circle with a slightly sticky tangling net of vines. There are no regular plants in The Wastes. Each vine/ tentacle is able to slowly move. Though they are easily evadable by a conscious adult. It allows them to capture and crush small creatures that disturb a vine (the corpse is crushed and vital fluids sink into the ground to be absorbed by various shallow runner roots). They are not great hunters. Their mobility is used for, well…. mobility. A Creeper can move at a slow walking pace in search for new water/ minerals or less acidic places.
Did we mention that Creepers live in herds or colonies of 5 to 20? They will move together in a large mass. This large mass and their mobility helps prevent the Verners from eating them all up at one time. Because they are eaten by the Verners (or insert other large omnivore/herbavore), they can not grow into large numbers. If they could, they could stabilize the semi-liquid soil, much the way real plants reinforce regular soil. But since they don’t, the Wastes are forever semi-liquid.
