The odour rising from the newly opened depths was intolerable, and at length the quick-eared Hawkins thought he heard a nasty, slopping sound down there. Everyone listened, and everyone was listening still when It lumbered slobberingly into sight and gropingly squeezed Its gelatinous green immensity through the black doorway into the tainted outside air of that poison city of madness.
H. P. Lovecraft
