They make an excuse to ditch Pluto, who then breaks out into a dreary song, but Earth cuts her off because her singing is causing Uranus to be put off of his strike. Nicole drives past the restaurant, getting increasingly fed up by the singing showerhead, before the scene zooms out to space, showing all of the planets making a joke at the expense of Pluto, but she picks up on it, to their embarrassment. Eventually, fed up with the song, Miss Simian bites Principal Brown's hands and ends the song prematurely. Miss Simian starts talking, but Principal Brown cuts her off and starts singing a ballad professing his love for her being covered in body hair (with help from Larry, however reluctant), much to Miss Simian's humiliation.

The spray-paint bottle talks to the 8-bit dog about how sad it was to watch a kid let himself go that much, but the 8-bit dog stresses that, being a background character, he has little to comment upon. Seeing this and believing the dolphin man, the spray-paint bottle, and the 8-bit dog to be the suspects, Billy decides to teach them proper etiquette in the form of a rap. Suddenly, a rat falls into her mug, so she tosses it out a window, knocking over a trash can on the ground in the schoolyard. Several citizens continue along with the singing while describing the woes of their lives, eventually leading to Elmore Junior High, where Miss Simian sings about how all of her students are brats.
