This egg was only available in Egg Cave's Cash Shop Park for December 2015.
This egg appears to be both blessed and holy. According to ancient Cave paintings, Dongelic eggs appear to be the first type of egg that is blessed by the Summoner.
According to ancient legend, Dongelics are the chosen method of transport by the Summoner and their Finders. Dongelics are both meek and submissive in nature but have incredible and almost godlike stamina to travel long distances.
While Dongelics appear to be among the most ancient of creatures on Ark, nobody knows why they went missing or how they just recently reappeared on Ark.
