Hittin' the Trail for Hallelujah Land

Hittin' the Trail for Hallelujah Land is a 1931 Warner Bros. Merrie Melodies animated cartoon directed by Rudolf Ising. The short was released on November 28, 1931, and stars Piggy.

The minimal storyline centers on the plucky Piggy's efforts to rescue his girlfriend and a doglike Uncle Tom from perilous predicaments and villains.

Why People Call it Looney Trash?
People call it "Looney Trash" because the short's use of the racial epithet "Uncle Tom" prompted United Artists to withhold it from syndication in 1968, making it one of the infamous Censored Eleven.

It is also considered Looney Trash because it's a ripoff of "Steamboat Willie" and the "Skeleton Dance". (Both cartoons are from Walt Disney)
