The physicians of the cave, who are presently attending to the being we've called "the monster," have reported the following:
1. The being is in fact a female amphibian named Mutio, who is of a highly-intelligent species called the Nereids (this name is derived from the sea maidens of Greek mythology).
2. Mutio was transformed into the fearsome form we beheld earlier by a poison which was introduced into her body via a venemous sea monster which attacked her.
3. She is now regaining her former body, via protocols which the cave people deem confidential.
In effect, Mutio will be her old self once again. With this good news also comes a marvelous account of how Mutio in particular and the Nereids in general came to be known.
Some years ago, a shipwrecked sailor who was adrift in the Pacific Ocean awoke from what otherwise would have been his final sleep to find himself being hauled onto the shore of a small island by "a sea creature." This sea being was in fact Mutio herself, who had taken pity on the human and attempted to save his life.
After regaining consciousness, the sailor was beckoned by Mutio to follow her to a safer distance from the water. She did not exhibit any vocalization, but communicated her wishes entirely via non-verbal means such as gestures and body language. (The name "Mutio" was given her by the sailor. He spoke to her on the assumption she would better understand his intentions by the tone of his voice.)
The following day, the sailor beheld Mutio swimming in the shallow water adjacent to the island. As it turned out, she was fishing so as to procure food for the human.
Here we see Mutio approaching the shore with a fish for the sailor.
Whilst recovering from his watery ordeal and awaiting rescue, the sailor noticed Mutio remained in the shallow water by the shore â€” closely observing him. The curiosity was mutual!The sailor determined the feathery appendages attached to Mutio's shoulders are external gills for breathing whilst submerged.
One night, during stormy weather, the sailor heard an occasional siren-like cry. During flashes of lightning, he saw to his dismay that Mutio was in distress at some distance from the shore. Unable to immediately swim to her aid due to the high seas as well as his lack of sufficient strength following his own recent struggle with King Neptune's domain, the sailor had to wait for calmer seas before venturing out to search for Mutio. He found her alive, but barely.
