Transcribed from recording labeled “Hik’kappu”:

Commonly found in the chest cavity of mammals, the numerous needle-like appendages of a fully-matured Hik’kappu not only serve as sensory organs, but also to stimulate what was once believed to be an involuntary contraction of the diaphragm.

Some researchers believe this serves little-to-no purpose, while others claim this is an effort by the Hik’kappu to coax its host into performing a rudimentary mating call.

However, the manner in which the Hik’kappu enters the chest cavity of a given host remains the biggest mystery of all.
