ahhh, it's in the mail!
So you might be at Coral World's underwater mailbox:
Currents is a convenient spot to purchase Coral World post cards for mailing in the world's first underwater mailbox. Drop them in the Underwater Mailbox in the Underwater Observatory (we will stamp them Mailed Underwater at Coral World). Open daily from 9:00 a.m. to 5:30 p.m.
