A song from the film and the book, Elya Yelnats had to sing it to the pigs because of a deal he made with Madame Zeroni. In the film when Stanley and Zero run from Camp Green Lake they find a stream, then suddenly Stanley sings the ''If Only, If Only song with a soft voice. The song goes,
If only, if only," the woodpecker sighs, "The bark on the tree was as soft as the skies." While the wolf waits below, hungry and lonely, Crying to the moo-oo-oon, "If only, if only.'' After Stanley was done singing If Only If Only softly this unknowingly lifted the curse that Madame Zeroni had put on Stanley's family, at the same time Stanley's dad found a cure for foot odour (Peaches and Onions).
At the end of the book, Hector's mother sings the full version of the song. Here is the second verse of the song:
If only, if only, the moon speaks no reply;
Reflecting the sun and all that´s gone by.
Be strong my weary wolf; turn around boldly.
Fly high, my baby bird,
my angel, my only.
