Extract all folders into your Creatures 2 directory.

WARNING: In later versions of Creatures 2 (such as The Albian Years), you will have to put the files in the "Creatures/Creatures 2" subfolder of your documents folder.

For example: "C:\Users\<Your Name>\Documents\Creatures\Creatures 2"

Run the game and check the hatchery, there should be two new turquoise eggs waiting to be hatched!
