Night Kid

Background
Described as a "dark and mysterious" attraction of the caverns who was half-man, half-bat. Night Kid was found in complete darkness and surrounded by bats. He was 2 feet tall, weighed 19 pounds, and had been feeding on moths to survive. The audio tour stated that the reason Night Kid was able to thrive due to the "abundant sources of shelter, fresh water, and bugs for protein."

In the Dead End part of the caverns, Night Kid was engaged in a standoff with federal marshals. He had grown to five feet tall and was captured by the marshals, subsequently kept in captivity for a decade. Night Kid was freed under "mysterious circumstances" and returned to live in the caverns.
