Historical dictators references:
The first duckling to hatch from the egg had a mustache and a Nazi emblem throughout the cartoon, indicating that the duck symbolized Adolf Hitler. The goose who helped the duck had an open Italian accent, and the chick at the end of one of his speeches could be heard yelling "Duce!" multiple times, indicating that this goose is Benito Mussolini. The other duck was using the flag of the Empire of Japan, and openly singing "The Japanese Sandman". He is presumably intended to be Hideki Tojo, judging by the military hat he is wearing. However, he is commonly misidentified as Hirohito.
