This egg was only available in Egg Cave's Cash Shop Park for April 2015.
This egg seems to be surrounded by feathers.
The Terapox was the first ever discovered link between birds and dinosaurs because of its feathers and ability to fly. It has been confirmed as the oldest bird species ever found. Terapices used to roam Ark City long ago but recently have be found more often as domesticated pets. Despite being a dinosaur, the feathers found on the Terapox are extremely soft. While this creature does have feathers, it is able to traverse the ground as well.
