Reception.
"The Film Daily" (May 13, 1936): "This musical comedy cartoon is a knockout. Following the opening, which is the song "Down by the Old Mill Stream", the impersonations are Cab Calloway and his band doing "Minnie the Moocher" routine, "Fats" Waller doing his piano number, Bill Robinson his taps, the Mills Bros. their "Hold That Tiger", Stepin Fechit is presented, and a dancing chorus does "Jungle Rhythm". The Technicolor is beautiful, especially in the water numbers. This short is just one load of entertainment all the way through."
"The Film Daily" (June 1, 1936): "In Technicolor, a swell interpretation by the frogs in the millpond of the famous colored artists of tap dance and orchestra. The leading lights among the colored entertainers are presented in fine imitations, the technique is very clever, and the entire production a real novelty in cartoon with beautiful color and catchy music."
