A Tic-toc is a kind of robotic bird, found throughout Gunnerkrigg Court. They get their name from the ticking noise their internal mechanisms create. No one knows who built them, or what purpose they serve. They are speculated to be some sort of surveillance network. They look something like a cross between a toucan and a parrot, with green feathers and a metallic grey beak. Despite the ominous ticking noise they make, their likeness to birds is strong enough that they were only discovered to be robots after Antimony Carver autopsied one of them.
