He said he had a "hatchling desert" out of his desert female. You stated "Female deserts cannot reproduce so it must just be a normal "

That, sir, is calling him a liar. You don't have to point a finger and yell LIAR LIAR PANTS ON FIRE to call a person a liar.

The picture you posted doesn't really look like a desert to me, but I'm no expert and it's not a great picture.
