Les shoggoths, indescriptibles créatures du mythe de Chtulhu de H. P. Lovecrasft peuvent changer de forme et prendre des proportions phénoménales. On les retrouvent entre autre dans le roman Les Montagnes Hallucinées. " It was a terrible, indescribable thing vaster than any subway train—a shapeless congeries of protoplasmic bubbles, faintly self-luminous, and with myriads of temporary eyes forming and un-forming as pustules of greenish light all over the tunnel-filling front that bore down upon us, crushing the frantic penguins and slithering over the glistening floor that it and its kind had swept so evilly free of all litter. ”
