So this is what i need that yogurt pot for - Alvim Correa's brilliant depiction of the Martians handling machine.
I plan on buidling it in this pose, set amongst Red Weed-encrusted ruins. Hopefully i'll be able to source some suitable scale birds from the railway modelling section.
Studying the picture, it looks like it has organic tentacles front, left and one coiled up at back. Assuming there's also one on the right that's either retracted or snapped off, I've drilled four holes in the yogurt pot and capped them with some wheel bits.
