An alluring melody can be heard flowing from within this egg. Musical instruments that are played to accompany this melody, particularly harps, will cause the egg to react by fluttering its wings in apparent appreciation. There is an ongoing study by the Science and Research Center to determine if the health of Harpette eggs are affected by various genres of music.
Harpettes are creatures that were once regarded as purely mythological beings until their recent emergence from Fairy World. Very little is currently known about them, but they have a strong affection for music and are excelled musicians of the harp. Ancient stories tell of how Harpettes will kidnap humans who are skilled with instruments and force them to play music back at their roost.
