Cybermat!

Being quite into Doctor Who at the mo' and fancying the idea of another biggish project like my Dianoga, i fancy having a go at a Cybermat.
Always liked the idea of them, and the fact that they changed their appearance every time we saw them.
This here is one of my favourite versions, so i had a think how i could replicate it.
The main body looks to me like i could use a food scoop of some kind.
Looking round the shops in two towns turned up zilch, so i got one off the 'Bay for a couple of quid.
I've hacksawed off the handle and next step is to remove the stub and sand it smooth.
Then cut the profile right,
put in the eyes,
maybe top spikes, maybe not,
and fashion the tail from Plasticard box-shapes
