this is some kind of spaceship or something.
“It’s a diorama depicting two space-traveling modern ponies discovering an ancient pony ruin on an exotic world,” says the artist behind this diorama, prepared for My Little Pony Project 2012, “I was going for a mix of Planet of the Apes plus Lost, meets Prometheus where the new Friendship Is Magic ponies discover a Stone Age relic of the original style of pony. This suggests they have encountered evidence of their prehistoric extraterrestrial origins.”
Let just hope they know better than to take off their helmets or touch any mysterious space goo. Seriously.
