Not just a catchy jingle! This pig is inspired by the book about anthropomorphized letters, who climb up a coconut tree in alphabetical order, until the tree collapses. Capital letters (the older relatives of the letters climbing the tree) come to help them. Again alphabetically, it describes each letter's injury, such as "skinned-knee D".

The book, included,  is notable for its rhyming structure which is reminiscent of the jazz vocal improvisation technique known as scat singing.
