Shoggoth

A Shoggoth is a monster depicted in the works of H.P. Lovecraft, the Shoggoth is almost always depicted as very large and frightening: in the words of Lovecraft himself:

"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."

The Shoggoth has become one of Lovecraft's most well-known and popular creations and appeared as a boss in the videogame Cthulhu: Dark Corners Of The World.
