You get up and take off your clothes, revealing a (color) bikini. The merman blushes slightly when he sees your perfect body. You try to ignore his stare and dive into the tide pool.
" You ready?" You ask.
" Yeah, what do I do first?" He asks, confidently.
" Hold your breath for as long as you possibly can." If this works as you planned you might be able to make him like being a merman.
The merman looks at you nervously, but obeys." Uh... okay."
He sucks in a mouthful of air before sinking under the water. You begin to worry about what you're about to do next. As his head slowly comes back up for air, you push it under so he can't come back up. He freaks and flails his arms. His tail flaps rapidly, but you still hold him under. After a few more seconds his body is still.
Oh my gosh, did you kill him?! You quickly take your hand off the back of his neck.
Come on, come up already. But he stays under. Crap, his dead. Before you can bring him above the surface, he comes up, causing you to yelp. He looks at you wide eyed and excited.
" Are you all right?" You ask a little worried.
" I...I can breathe... underwater," He says in awe. "I can breathe underwater! I have the power to breathe underwater! This is awesome!"
You smile at his enthusiasm as he tells you about what it was like to breathe underwater. He blushes and smiles nervously as he notices he's babbling. Then he asks you," How did you know that I'd be able to breathe underwater?"
" I didn't. I was just hoping to murder you," you say, smugly. The merman just stares at you in shock. You playfully punch him in the arm."I'm just kidding. I just thought you might be able to breathe underwater like the mermaids in the movies. And it's a good thing you could too. I was starting to think I really did murder you."
"Yeah, good thing."
You both start to swim in silence for a while before he asks for another test.
" Well, there is one more."
