Long, Tall, Grey Alien

So, what do you recon this monstrosity is made from? Didn't take me too long and I intend making four in total for my games of Five Parsecs from Home. Added all the armour, made from green stuff and the weapons come from Tau and Catachan models. The head is that of an Ork and the basic structure is...

Yep I went out and bought this huge bag of plastic animals from a cheap department store for £2.99, mainly so I could use the tigers and lions and bears as fillers for other armies, but then I saw the giraffe and the rest just came to me. Silly, but fun and very cheap. I can see the Gorillas getting large bazookas attached to their backs!
