The first one is where you land when you dident save all the 300 Mudokons. Its basically the place where you get the bad ending. If you dident save anybody the trap door leading to the second level will be shut and then when you land on the first level you have to deactivate those mines and jump in the bird portal and get the bad ending. Thats all it is. Yea at first I never knew what that was all about but when I tried for the bad ending well there we go.
