Grab 8 or 9 pe parts,the type used for joints and place them like this on a thick piece of rod.
Now don't all laugh at once but get a cheese string wrapper and cut a good length from the crinkled back part and glue around the tail.
Next get some garden wire,cut into small strips and wrap them in between the pe parts so that it has a puffy appearance.
Leave one end hanging for strap ends.
Next up get get some screw plugs/screw covers, not sure of the name so that's what i'll call them, cut each one in half and then snip a small bit of the sharp tip on the edge to smooth them out.
Then place these down the tail.
The part on the end of the tail is a 1/60 patlabor head sensor.
Use some 1/72 tank tracks and cut these in half and place them on the ends of the garden wire to give the appearance of straps.
Then glue the tail at the back,all done
