Question that i can't seem to find the answer to.

How many boats/sharks/ect. should be under the beach/land/citadel tiles?

What i mean is, how many sea monsters should have been revealed when all the beach tiles are gone, and how many ships and so on. I just got a copy of the game and there are only TWO tiles that show a ship and there are 8 whirlpools and only 3 octopi total. That can't be right. Could someone tell me the appropriate combination for each kind of tile?

Thanks!
