Yes - isn't it just!

Hmmmm - yes - I've seen that in toys like Furbie - every movement has some
kind of bendable structure or slipping clutch between the drive system and
the exposed parts. I guess that prevents small children from being bitten
and saves the toy from the worst of the damage it would otherwise suffer.

Yes - I guess I'll need both - just a plastic bag by itself wouldn't work
because it could still be 'injested' into the geartrain and given the number
of holes in any Technics structure, there would always be a route for small
bits of fluff to get into the mechanism with just a bunch of plates snapped
around the major components.

I'll keep everyone posted if I manage to get something to work.
