A muttering dead organism ;
I envisage a dark rotting mass with bubbles raising, which on bursting make noises similar to Tomatoes; impositions; pink gins; its not fair; come the revolutions; listen to me; listen to me; is anyone there; etc..etc..etc.........
The whole surrounded by linked bassa lanyards with warning notices 'This could happen to you!!! join an onion'
With apologies to shades of 'Monty Pythons Flying Circus' for those young enough to remember.
