Dumbo has more that one potentially problematic sequence in it. The Song of the Roustabouts sees several clearly African-American workers putting up the circus tent while singing about their lack of education and penchant for drink. The end of the film sees a collection of crows that speak in a jive-like dialect, the leader of which is actually known as Jim Crow, which is, just, just awful. There had been early reports that this infamous sequence would actually be removed from the Disney+ version of Dumbo but the movie on the service right now is unedited. Instead, this disclaimer prepares the audience for what they're going to see.
