Earthworm Jim 3D/Memory

After you have obtained your first Golden Udder, you can go into Jim's Memory of the farmyard wars. When you first enter, there will be the Cow of Contemplation in front of you. Talk to the cow and you can then enter the first level: Coop D'Etat. There are other levels here which require a certain amount of marbles to unlock. This is covered in more detail on the intelligence page.
