Mayby you'll know the Guests statue pack.
The pack wich makes it possible to place guests in different attitudes as a statue.
This is pretty nice when you want to give your pc a little bit more memory, because the real guests takes normaly a lot of memory.
But guests do gives donations and statues don't.
At least until now!!
Because in V1.1 of the first part of the guests statue pack this is gone.
They'll give each day some money to your zoo as an donation.
Also there will be new icons in V1.1, wich finaly makes an end of the extreme ugly (test) icons, how where an mistake.
So take a look some day on the page of the guests statue pack!
