The Barren Wasteland is the main location of the entire Salad Fingers series. It appears to be a desolate wasteland with very little to no vegetation that isn't hospitable in any way. It is the main setting of the series.
The wasteland is mostly a large barren area of complete dirt and sand with no healthy vegetation anywhere in the videos. There are weeds and trees, however due to the lack of visible water it can't be certain how much is in the area. Due to the fact that Salad Fingers blood is red and liquid, there is water in some location nearby (even if it is muddy).
