>>13104 Might be fun to put together an Equestria evolutionary tree.

Some possible headcanons: Crystal Ponies have physical states that are governed by their emotional states. Their natural states are as liquid in the ground. They can emerge and form solid bodies dependent on these emotional states. When they are happy their bodies are soft. When they are aroused they melt back into the ground. When they are frightened they become brittle and tend to shatter. When they are mad they become hard like diamonds. and when they are sad they become light and ephemeral to the point that when they are despondent they fade away.

>>13110 >When they are aroused they melt back into the ground. Wouldn't that kind of get in the way of things? Or do they do their business underground?

>>13111 Well ok, you're correct of course. I've wondered about this myself. But this can be the 'TV - 7' version. Yeah, they melt back into the ground to conduct their business. For the TV version: When they fall in love their bodies give off a rosy glow. When they are sad they give off a dark blue glow. When they are despondent they turn black.

>>13110 >When they are aroused they melt back into the ground. See, I thought it would differ by gender. Females become soft (yet supple and durable), while males become hard as diamonds.

>>13119 Or maybe they're just like a mood ring instead?

Crystal Octavia a cute!

Why did the Crystal Empire have crystal gryphon statues guarding the libraries entrance?

>>16515 Maybe they had trade with the Griffons back when the Griffons had a thriving empire? Maybe they were a gift from the ruler of Griffonstone at the time.
