As you were escorting the tycoon, specific number of voices utter a big amount of numbers catches your attention.

Two guards opened the entrance door and you see there is many people bidding on something in a large tank... A merman?

"200 million."

While patrolling around, you hear a tapping sounds from inside the tank, the merman is trying to get your attention. Can it even communicate with human?
