"Wait", you suddenly consider, "I didn't think of something...I don't even know how mermaids are supposed to behave, even though I am one." You quickly swim back and the frogman is already waiting for you. "I was about to say", he smiles, "the costume can hide your body, but not your mind. That, you'll have to learn from a natural female." He lets out an odd-sounding series of throat clicks, which sounds like a signal. Suddenly, from the muddy water a frog face leaps up, though somewhat sleeker and finer built than that of the frogman. "You called?", it asks in a surprisingly sweet voice. "Yes, this young lady here is going to be our spy...but she has no experience with anything ladylike, so if you could help her a bit with that it would be appreciated." The figure now rises completely from the water, and you immediately notice she has two round breast lumps, covered in green slime. She notices your eyes fixed on them and says:"Yes, oddly they don't disappear when females transform. Makes it a lot easier to tell male from female though." During the time she has been talking, you've noticed her round eyes were locked onto a buzzing fly, and with a sudden snap her tongue darts from her mouth and reels the fly in. "Oh, I'm sorry...force of habit", she quickly apologizes. "Now then, shall we get started on getting you more ladylike?"
