Sliding Worm

A caterpillar-like monster that propels itself forward by contracting and stretching its huge body. Just one such move will propel it as far as a grown man's stride, a fact which inspired its naming. Its stolid appearance belies shocking swiftness, and it can move with fantastic speed as it writhes. If you do not run with all your might, you will not escape this beast. Before you know what has happened, you will have been overtaken and will feel the sharp teeth lining that mouth digging into your flesh.
