I think that I figured out what's been happening with the diver thought bubble issue. Some people have a diver in their sale tanks - including me - and still see a question mark next to the diver in the thought bubble.

In one of my games, I have every ornament available and stuffed into the sale tank.

I never see the "where's the diver?" thought bubble anymore, but I still saw some of it in my other games where I don't have all the ornaments.

It is my belief that although the customers' thought bubbles shows a diver, it may actually be any one of the other ornaments - such as the sunken ship, the shell, or the Grecian columns. The program, however, has limited graphics for the thought bubbles, and in this case, it seems that there is only the diver graphic for the ornaments.

In other words, when customers are thinking, "where's that diver?" they're really thinking, "where's that ship?" or "where's that cute shell?"

The situation with the fish types might be under the same constraint. So far I've only ever seen them think about goldbulb, fatfish, or pink fruitfish.

<shrug> Just my take on the situation.
