OK, so quick question here.

Seeing as the big event just ended, and I had nothing better to buy, I blew all of my remaining magic on Eggs of Mystery.

On my second one, I got a Hidden Bolt dragon. The egg's currently in my nursery...

And it's a twin egg.

I know these can't be bred, so is this extremely rare?
