Trivia: Disney's first direct-to-video animated sequel. Releasing it direct-to-video was considered something of a gamble at the time, as producers worried it would cheapen the Disney brand. However, the gamble paid off - it sold incredibly well, and went on to become one of the best-selling VHS titles of all time, eventually making back over 50X its budget in profit. After its release, over 50 more direct-to-video animated Disney sequels were produced (if one counts both 2D and CGI movies).
Trivia: "Three Little Bops" marks the first time that anyone other than Mel Blanc was credited for voice characterizations. Stan Freberg provided all the voices in this cartoon.

Trivia: Near the end, during their extended nonsense bit about the stolen Beaugard painting, both Chico and Groucho were rapid-fire ad-libbing so heavily that they became irritated with one another. In fact, by the time Groucho ad-libbed, "I'd buy you a parachute if I thought it wouldn't open," he was getting really pissed off at Chico's faster and funnier come-backs. Almost instantly, Chico shot back, "Hey, I already got a pair-uh-shoes!" (which was, again, funnier than Groucho's parachute line). At that point, Groucho snapped and sprang into some improvised physical comedy, falling backwards across the card table and elbowing Chico right in the face, perhaps on purpose. Genuinely shocked from the blow, Chico recoiled wide-eyed, looked toward director Victor Heerman off-camera, and angrily exclaimed, "He's crazy!" (referring to Groucho).
Trivia: Despite having only 17 minutes of screen time, Spencer Tracy received the first of his nine Oscar nominations for his performance as Father Mullin in this film.
