I have two questions. 1}How do you get toxic sacs, thunder sacs and inferno sacs not poison, electro, and flame sacs. It says I need 10 Toxic sacs to upgrade my hammer. If it helps anyone who has the Kirin Bolt Indora will know how to get thunder sacs. 2} How do you get rubbberyhide plus. Do you combine or is there a different colored Gypceros I need to kill. PLEASE HELP!!!!!!
