Wombling explained below, straight from the Womble's mouth.
Underground, overground, wombling free
The Wombles of Wimbledon Common are we
Making good use of the things that we find
Things that the everyday folks leave behind
Uncle Bulgaria He can remember the days when he wasn't behind the times
With his map of the world
Pick up the papers and take 'em to Tobermory
Wombles are organised, work as a team
Wombles are tidy and Wombles are clean
Underground, overground, wombling free
The Wombles of Wimbledon Common are we
People don't notice us, they never see
Under their noses a Womble may be
We womble by night and we womble by day
Looking for litter to trundle away
We're so incredibly utterly devious
Making the most of everything
Even bottles and tins
Pick up the pieces and make 'em into something new
Is what we do
Underground, overground, wombling free
The Wombles of Wimbledon Common are we
Making good use of the things that we find
Things that the everyday folks leave behind
