Texas certainly has no shortage of swimming holes to explore on hot summer days, but not all of them can also claim to be the longest underwater cave in the whole state-- that honor is reserved for Jacob's Well in Texas's Hill Country, right smack dab in between San Antonio and Austin in the small town of Wimberley.
The best answer to this question is found in Lovecraft's tale The Call of Cthulhu. Cthulhu is a monstrous entity who lies dead but dreaming in the city of R'lyeh, a place of non-Euclidean madness presently (and mercifully) sunken below the depths of the Pacific Ocean. Cthulhu appears in various monstrous and demonic forms in early myths of the human race. Racial memory preserves Him as humanity's most basic nightmare. Cthulhu is the high priest of the Great Old Ones, unnatural alien beings who ruled the Earth before humanity formed, worshipped as gods by some misguided people. It is said that They will return, causing worldwide insanity and mindless violence before finally displacing humanity forever.
Strategy. The Eye of Cthulhu has two phases that it goes through as it does battle with the player. The first phase, a giant eye, has 15 attack power and 12 defense, while the second phase, a giant eye with a gaping jaw in place of its lens, has a 23 attack power; however, it has no defense. If The Eye of Cthulhu is summoned during a Blood Moon using a Suspicious Looking Eye the Dryad may not spawn. 2  On the Console and the mobile edition the boss 4 music will play instead of the boss 1 music (May be intentional).
