Toc Toc is a clockwork engine who holds the secret to the tick and the tock.

Little Titch, Gideon, and Minnie Millie come to the Clockwork Village with a cog, spindle, and wheel to fix the Great Clock.

But what lies behind the towering clock face? And why, for a clockwork village, is there neither a tick nor a tock?
