Drei Caballeros im Sambafieber

This more than any other film shows the plight of the Disney studio in the years following "Snow White" and "Pinocchio".

WWII had broken out, cutting off Disney's European market. In addition, striking cartoonists and their formation of a guild/union meant that the massive about of labor needed to create a "Snow White" or a "Pinocchio" now amounted to a substantially higher production cost then either of those two films (which had not been cheap to begin with).

Thus, Disney was trying to explore new ways to both package his product for another market, as well as develop new product.

They released this movie and capitalized on the then-popular South American craze. Now, however, it looks dated.

You can still it watch it though and see the genesis for several of Disney's later films: "The Three Caballeros" and the whole "How-To" Goofy series are the most obvious.
