She chuckled at his statement. So, he either caught on, or was being genuine. Well in the end... getting him what he wanted would be so easy for her. She already knew where such items lie-- and with so much sand. She almost purred at how easy this would be.
Then, the ground started to glow. She looked at the light, and how it sucked the lives of the plants and small critters in it. She chuckled and looked to his face. "Aa.. immune to my body?

I don't dress like this to lure people in."
She waved her hand and held it out like she was holding something. A small tornado of sand lifted from the ground and swallowed her hand, dying out to show she was now holding a dragon's skull-- a baby's, but it was for the show of it. "I know what you seek. And, I know where to find them. A lot. Bigger than this small creature's, that's for sure." Though, she held the skull out to him.
