Octopussoir

The Octopussoir is a monster that was Princess Clara's vagina. When Clara was very young, her Evil Stepmother put a curse on Clara's vagina, causing it to turn into a hideous, tentacled (and male) monster. Despite its frightening appearance (which makes nearly everyone vomit the first time they see it), the Octopussoir is actually quite kind, only attacking people when it is frightened by loud noises or provoked in some fashion. When the housemates first found out about it, they wanted to kill it, but came to accept it once they realized how kind it was. Still, Clara never got over the stigma she felt not having a normal vagina, so she got rid of it through plastic surgery. She eventually reconsidered, but when she tried to get the procedure reversed, Octopussoir told her that he had moved on, having completed college and married a 38-year-old Jewish woman who was quite possibly Unusually Flexible Girl, and was quite happy in his new life.
