Thanks! I was wondering what this issue was called. Thankfully, it's pretty much the only flaw as far as this pony is concerned.
As to not spam the board, the second pony has tiny gouges all over her body, all the size of pin heads.I was going to try boiling her to see if these pin prick holes will sort of work themselves out. If not, I got Sculpey III and hopefully a hot water set will help the clay harden without baking it.
