The Mysterious Feather
On November 2009, a mysterious feather closely resembling a Calla was discovered. It was said that it could lead to the Calla's full discovery. Ark citizens were asked to make donations of EC (the currency of Egg Cave) toward the study of this feather so research could continue.
On November 2009, after the funds had been met for the first request, it was announced that the Science and Research Center would need 500 million more EC for equipment, however once this goal was reached they may be able to reconstruct a Calla from DNA in the feather.
