Try to escape

The pool is where the most mixing goes on between the different demon types. Though you noticed something unique, swimming around the pool is a mermaid!

For a brief moment she makes direct eye contact with you! Your heart skips a beat and you feel like you might be in trouble and turn to flee!

That looked, it seemed like for a moment she noticed you weren't as mindless as the other girls, she noticed! If she is working for the demons, you are in big trouble...But what if she isn't. Could she be an ally?

Having checked the entire place, you realize you are not getting away, not without help. You will need to risk speaking with the mermaid.

You casually slip into the pool next to some demon girls who are making out. The mermaid spots you and swims over. She smiles as she rests her soft tits on the ledge of the pool. "Hello dear, you seem to have some senses about you...Listen carefully since we don't have much time, we will be in trouble if the imps find us talking. I can help you get out of here, but you need to help me. There is a secret level that drains the pool, you need to find it!"

You now have a plan, something you can try to do!
