Tritentakla

The Tritentakla is a massive, unnatural creature that roams the Fire Hole Basin.  It wades in and out of the hot spring’s mineral-rich waters on three elephant-like legs with three tentacles that come out of its torso which is mostly a large toothy mouth.  Two tentacles end in barbed flipper-like appendages while the center one has a patch of eyes able to turn and see all about.

First spotted in the Fire Hole Basin in Tasset.
