Some concept art of the Tentacle shows it to be a cluster of three Tentacles attached to a bulbous base, which matches that encountered in the game.Īlthough Tentacles usually come in groups or clusters of three, single Tentacles are also encountered, and the number of Tentacles present may reflect the size or stage of development of the base, or else a more spread-out being, with Tentacles in various locales. The Tentacle's body encountered at the bottom of the chasm is somewhat squid shaped, with three stumps that appear to have been severed.
