This a motorised forklift truck, it comes from previous bloggee Vladimir Drozd, and it is quite good at squashing Elves.
With a number of our smelly little workers distracted by something shiny, the Elven discoverer of this creation snuck up and dropped a box on them. Because it could.
Doubtless a victim of past smushings, it enjoyed being the perpetrator immensely, and is now happily eating an orange Smartie whilst we patch up the victims.
A pair of Power Functions motors raise and tilt the forklift boom (enabling a brick built box to tip smartly onto those underneath), whilst a further two motors drive and steer the truck itself, and there’s more to see at both Flickr, Eurobricks, and via the video below.
