Elvis Presley's song, Hound Dog, was played twice. One was when Howler was playing his piano and another time was when Penelope, Cooler's ex-girlfriend, sang to him in Cooler's Flashback.
Most of the plot is inspired by the movie Casablanca.
In the beginning of Cooler's flashback, Scrounger, Violet Vanderfeller, and Barkerville from the Pound Puppies TV Special make a brief cameo appearance.
