Babies:
To make a baby animal of any species, build an exhibit. Go to the Adopt an Animal. In between the middle and the bottom you will see three golden symbols. Click on any species, then the circle with the arrow. Put two animals in the exhibit. Then click on the circle with the cross on it. Put two of that species in the exhibit. Then try to make that species really happy and you will get a baby.
