Chronophage!

Terrifying time-eating monster invades Scottish museum

Alright, it's a clock in the form of a terrifying time-eating monster, but still... yikes. Clearly someone in the Museum likes terrifying clocks, because it'll be down the hall from this history of the 20th century's wars which plays a jolly song every four hours.

Clocks are of course a recurring theme in Doctor Who, as are beings that interact with time in unusual ways. They're generally called Chronovores rather than Chronophages, of course...

But I'll go and see the Chronophage soon. And I'll keep an eye on it...
