This film is the first in the "Looney Tunes" series. Honey makes her first appearance. Bosko makes his first appearance in a theatrical film, and his second appearance of any kind. (His first appearance was in a demo reel called Bosko the Talk-Ink Kid (1929), which was never released commercially.)
The song "Singing in the Bathtub", sung here by Bosko, was originally introduced in the Warner Bros. feature Show of Shows (1929).
The cartoon's opening credits originally had the legend "A Hugh Harman & Rudolph Ising sound cartoon," then changed to "A Hugh Harman-Rudolph Ising musical cartoon" with the following short Congo Jazz (1930), and eventually changed to "A Hugh Harman-Rudolph Ising production."
The scenes in which Bosko's mouth fills the screen and he splits into miniature versions of himself were previously done in Bright Lights (1928), an Oswald the Rabbit cartoon that Hugh Harman and Rudolf Ising worked on whilst they were at Disney.
