Tar-Baby
From Gnomon Chronicles

Turpentine still, used to make both turpentine and tar. Tar from the still shown here has produced a notoriously sticky breed of tar-babies.
A Tar-Baby is a demon which has possessed a tar-baby.
Turpentine delight
Tar-Babies enjoying feeding on Turpentine delight.
They also enjoy feeding Turpentine delight to others. Tar-Baby 9000 is notorious for this.
Invariably, having fed Turpentine delight to others, a Tar-Baby will then feed on said others, chasing down this morsel with a generous shot of Extract of Radium. Hirality ensues! (Not!).
