Serena's announcement led a lot of people to start planning. If they catered to the needs of the Mermen, then they could get Sand Dollars in return.
And with those Sand Dollars, they could buy all the Soo drops they needed!
This applied to all companies, even those that weren't in particular need of Soo drops. After all, they could either trade Sand Dollars or Soo drops to other companies who wanted them in exchange for something they needed.
Many foresaw Sand Dollars becoming the new trade within Metropolis.
And the best way to obtain those Sand Dollars was coming up soon.
The parade welcoming all tourists would be the best chance they had of enticing mermen to spend their Sand Dollars in their store.
…
After the party, Serena and her Mermen were escorted out of the auction house and back to their temporary dwelling a few ways away from Metropolis. They needed sea water to sleep comfortably through the night.
