Ray Bradbury,
Futuria Fantasia, Winter 1940
“ Beneath me was a limitless tract of grey slime which rose and fell torpidly as with the breathing of a somnolent subterranean thing. The moonlight burned brightly on it, and crawling across it from some remote place came—trees?—snaky-rooted things whose prehensile branches bore, instead of leaves, flexible lenses.... They left behind them red trails on the slime, and excrementory ribbons of thin blue vapor streamed from their topmost appendages. Occasionally they paused to feed, focussing their lenses upon the gelatinous ground, which became luminously white under the concentrated light. ”
