No, it's not a giant gorilla - it's a giant Robot Gorilla!
My brother knows I like giant monsters, and someone had left this out with other junk to be thrown away, so he grabbed it for me :) A new paint coat, wash and highlights later, and I've added some metal and glowing eyes to turn him into a robot monster - titanium breastplate and all!
Part of a hairy cybernetics experiment, the misunderstood machine goes on a rampage through the streets of future London, falling in love and running off with one of the Doctor's damsel companions clutched in its massive paws, etc... Sounds like an idea for a scenario to play out at some point :)
As always with metal, the metallic painted parts look heaps better in real life than in a static photo.
