A set of plastic toys
Includes a variety of colors and shapes, some imitating animals, etc. Distinctive by their round bottoms
that enable them to rock back and forth, without falling over
Hence, the oft-repeated commercial jingle:
"Everybody loves a weeble,
Weebles wobble, but they don't fall down."
This song is often sung outside bars early in the morning as people do very bad weeble imitations. Bad in that they do actually, well, you know ..
