Wow.
E.G. brought back this super-cool toy for sozlet from Japan, when she was still a little baby (6 months?). It was a nipple.
Seriously, it was a rubbery, squooshy, flesh-colored nipple + areola, with a face on it -- the nipple was the nose, then eyes above and smile below. It was backed with some sort of purple plastic, with handles on either side, and squeaked when squeezed.
Babysoz adored that thing, though it gave her unpleasant ideas about what
I'd do when squeezed (ow).
