I do not know ...

In some ways , those eggs have similarities typical of different species ...

F ish or amphibians possess similar characteristics , such as the transparency of the egg which allows to observe the development of the embryo in its interior , but these eggs require water in order to survive and develop , but here we are in a dry ( a cave , I think) so I would say that this hypothesis is to be discarded .

In the same way you might think of a colony of changlings , since they possess inherent characteristics of insects ... but in this case I have to ask where are the " changlings workers " , or as they are called changlings those that deal with the management of brood ... ?

In addition, the silhouettes of the embryos glimpse to me the presence of anatomical details typical of reptiles ...

Perhaps our Applejack has discovered a brood of an unknown species ... or maybe a forgotten civilization of reptilian- pony ?



The fact that she has that look so frightened , I think this comes from the fact that one of the embryos seem to observe her from the inside the egg ... and actually , combined with the general context , this is something quite creepy ...
