An anthropomorphic bat flies into the ground, greeting you with a friendly manner, although somethings off, she extends her hand out for a handshake.

"Hey there, name's Rouge, you got any diamonds and rubies? I'll just... borrow them, heh, nothing personal."

The bat uses her looks to manipulate you into giving her the gemstones, after which if you gave her them, she'd probably not care about you one bit, although it was very clear that she was lying, she didn't seem that nice.
