A guy is murdering children and stealing their hands to turn into piano-playing automatons. And we actually see the results of his experiments on the front cover.
The casual, Shou Tucker-esque way he discusses his plans to Jerry, as if he sees these atrocities as a simple art project.
While he definitely had it coming, Toggle's fate at the end of the book. The ghosts of his victims rise from the pianos, take back their hands, and then drag him screaming into the forest out back, never to be seen again.
