There were fewer commercials on network television when this special was made. When shown recently on ABC and ABC Family, sometimes the special is edited in order to accommodate more commercials. In the ABC version, the songs "If you Sit on My Lap Today" and "My World is Beginning Today" are cut, while the ABC Family version cuts out scenes that may be traumatizing for younger viewers, most notably the scene where Burgermeister Meisterburger burns all of the toys belonging to the children of Sombertown.
The story is set in Germany and all of the characters are necessarily Germans but only the evil characters actually speak with German accents or have stereotypical German mannerisms. The other characters are depicted as being essentially Americans.
In the shooting script, the penguin's name was Topper and that was his name in the original broadcast. In some later broadcast versions, the penguin's name was changed to Waddles for unknown reasons. Current broadcasts and all home video releases have reverted the name back to Topper.
