There's a strange humming noise that comes from this egg. It sounds harmonious and musical, too.
The Volpe is known as "The Harmonious Fox" that seeks to live in balance with nature and all of its surroundings. It is a vegetarian animal unlike the many other types of foxes. As a result, it isn't the type of ominous predator that you would think it might be.
A musical staff, similar to the Pekva, is imprinted on the wings of the creature. The various lines that make up the wing (staff) can actually be plucked like a string. They even make a sound like a harpsichord! Their wings, however, are very delicate and fragile and cannot be plucked regularly. Otherwise, the wings will be covered with debilitating sores and bruises. If a Volpe's wings are plucked too frequently, it can permanently disable the creature, making it impossible for them to fly.
Under humane and strictly regulated conditions, samples have been recorded from Volpe wings and digitized. In the shops of Ark City, you can buy electronic Volpe Keyboards if you desire the sound!
