I got back to RuptureFarms to the place I couldnt get on the start of the game and it says on the wall "take us to the birds save us all" or something like that, and when I save it's called Rescue Zulag.
The problem is that I've done everything I can and I still cant seem to open an electric door that on the same screen with the mud that chant and gives you the red power. I think I shouldve used the sligs to talk to the slogs but I killed all the sligs, and I cant pass the slogs which keep coming no matter how much of them I kill.
Any ideas?
