Koohii stories:

1) [Thaliel] 8-7-2006(145): Spine connects head and body.

2) [Senshi] 20-7-2007(54): The spine goes from one opening mouth/opening (mouth/face) to another mouth/opening (genitals). Just think of these openings being enlarged to represent the head and the body. The bottom is bigger because the body is bigger than the face.

3) [MichaelAnd] 10-3-2008(37): The spine goes from one opening mouth/opening (mouth/face) to another mouth/opening (in your ass).

4) [aoerstroem] 21-10-2007(22): I looks like two vertebrae connected by nerve threads.

5) [terozen] 25-3-2012(10): In "The Human Centipede", one spine connects two mouths to keep the food circulating.
