Today’s Celestia Challenge is Elemental Ponies!!

We’ve seen a firepony! We’ve seen Windigos, which are basically wind or frost ponies. So what other elements could we see on ponies? An interesting take on an earth pony? Maybe a lightning pony or a water pony? Be creative and draw whatever element you want as a pony

You have 30 minutes to draw, then 15 minutes to submit! Have fun!
