If you have a norn egg or norn that is already born to get the replication power pick ups. Then recycle Some things to get bioenergy. Then you could create things. Make sure it is the slug gun. Get about 5 of them. Then there will be a sludge gun where the norns live. Then put then in the Learning place or near the portal. Make sure you connect them together. Press the icon that looks like a capital a. Press a button that will show you where the creatures are at. Click on the grendel. When a grendel comes just shoot it with the sludge gun to make it die.
