Early on in every episode, usually after Mr. grouper tells the Guppies (and viewers) about a certain subject, a song will begin to play. This is known as "the pop song". Sometimes near the end of the episode a reprise of it may also play, like for example, A Bunch of Bones.
While others have sung the Pop Song, usually it is Molly who sings them.
