The irony there is that the original 1964 New York and 1966 Disneyland versions of the ride had more human dolls in the Africa scene.
But they were removed when the first wave of 20th century offended people complained the children were laughing along with the laughing hyenas and that allegedly showed that African children were just like wild animals. Or something? But the laughing children with the laughing hyenas were removed, leaving the Africa room with fewer humans than it had originally.
Here's the original scene setup with the four dolls laughing with the hyena who were removed later in the 20th century.
The Africa scene actually has a lot of dolls still left, mainly because of the turntable with the tribesmen doing the Twist up on the turntable, and many musicians perched up along the walls and upper sets. The removal of the laughing children down in front left that scene looking more bare closer to the boats.
But I think it's fairly obvious where any human representation of Africans is going in the parks. They will be removed entirely, and Disney will give it all the Lion King treatment and just pretend that Africa only has animals there and no living humans or human culture to reference or portray. Problem solved!
Now, about that little Dutch boy knocking his wooden shoes together in that topsy-turvy tulip...
Honestly, every single doll and set in It's A Small World is a cartoonish stereotype of the country/culture/continent it's portraying. How anyone could be offended at any of this is beyond me.
Except for the Canadians. That entire country has no dolls, no sets, and just a plywood Mountie flapping his arms in a dark corner.
