It was red and dripping; an immensity of pulsing, moving jelly; a scarlet blob with myriad tentacular trunks that waved and waved. There were suckers on the tips of the appendages, and these were opening and closing with a ghoulish lust…. The thing was bloated and obscene; a headless, faceless, eyeless bulk with the ravenous maw and titanic talons of a star-born monster. The human blood on which it had fed revealed the hitherto invisible outlines of the feaster.
—Robert Bloch, “The Shambler from the Stars”
