A greatly feared beast that resides in small shaded bodies of water. Preferred habitat is a cave with a waterfall covering the entrance. The Grotto Monster will spring upon prey and destroy them with powerful jaws and arms eating nearly every body part. Due to ferocious attacks he remains perhaps one of most feared monsters in Northern California although he has been spotted several times in southern California.

No one has every captured footage of the Grotto Monster, because no eyewitnesses are ever found. The earliest recording of the Grotto Monster's Legend is somewhere in the early 1980's. Although the sources are plentiful they remain spurious.
