I'm not having much search luck this morning.  Is there a list of how many objects fill actually fill each floating object category?

For example, I have six kinds of dwarfs but there is still an empty hole in the center that looks like room for a 7th so I keep collecting dwarfs.  If there are only six I'd like to stop collecting them and focus on other critters.  Is there a list somewhere showing the total number for each FO type?

There are only 6 dwarfs.

Do you know of a list of all the floaters?  Do they all have six?

Some have 9. They show what you need and when you catch one it fills it in. You don’t fill in empty spaces.
