"Skin on Our Teeth" plays at the end of every campaign's finale to keep the players on edge when the rescue vehicle has arrived. The theme appears to be a modified section of the Tank theme to set a similar but more urgent mood. The name is a play on words of the well known phrase 'Skin of our Teeth' meaning to just barely achieve something.
