Footage has been released of an extraordinary Halloween stunt on the Clifton Suspension Bridge.
The 200ft 3D animation followed the story of two graffiti artists spraying the underside of Brunel's bridge who disturb a troll living there, only to incur the full force of his wrath.
The troll breaks out of the rocks wearing a Brunel-style hat and smoking the architect's trademark cigar, before jumping into the water below.
The monstrous mischief was a joint project from Bristol-based creative agencies Taxi Studio and Play Nicely.
You can watch a short clip of the ghoulish spectacle here:
