This morning one of the guys at work showed up with a doll for his kid. Look, he showed me, it pees and poops! I turned it over and sure enough, it did. Looking at the box, I saw the thing was a product of a major toy company, to boot.
It reminded me of some of the other toy ideas that passed before our eyes, back when I worked in R&D at Milton Bradley.
For example, there was Baby Black And Blue. BB and B had a special plastic skin, that changed color if you grabbed her by the legs and whacked her hard against a tabletop. Just like a real baby.
That one never saw the light of day, or the light of stores.
Then there was Feed the Alligators. That was a two person game, where one kid operated the mouth on a wooden alligator, and the second kid operated a little seesaw that launched little babies toward the water.
I remember playing that game for real, when the big bully kids would launch me and the other tykes off our seesaws. We learned to exit fast when we saw them coming, lest we go aerial.
F t A was actually sold, for some years. You can probably buy a copy yourself on ebay.
