Magic Roundabout and Emintrude gets Mad Cow disease,

When did spitting image do a p@@take on the Magic Roundabout? It was when Emintrude got Mad Cow disease, and killed all the characters off, and at the end, the roundabout had coloured coffins.

I know its sick but I thought this was one of the funniest thing spitting image has created.

Where can I get a copy of this?
