I think we can all agree that there are some toys that are just more popular or memorable than others. The Monchhichi toys were super popular when we were kids, and while we remember them fondly, we don't really know much about them.
The Monchhichi franchise was first launched in Japan back in 1974 as an update to an older toy called the "Kuta Kuta Monkey". They were apparently created to "inspire respect and love in the young children".
The name is supposed to be a combination of "Mon" (french for mine/my) and "Chhichi" which apparently is based on the sound a pacifier makes when a child uses it. When it's read in English it basically comes out sounding similar to "monkey".
In 1980, an anime series as created about the characters called Monchhichi Twins. It wasn't until three years after that that these little monkey-type creatures officially made their way to America. Mattel bought the license and Hanna-Barbera created a show that would help sell the toys.
Kids loved the toys but apparently not enough. Mattel stopped producing them in 1985, but it eventually had a little resurgence in the early 2000s. Even though they weren't on the market for long, they still had a huge fan base who seems to still remember them fondly to this day.
