Other poems, illustrated by the Sesame Street cast, include "The Strangest Word," "When My Imagination," "The Mystery," "What Is a Song?" "Oh, I Was So Embarrassed!" "There Is a Road," "There Is a Place," "I've Been Wondering," "When You're New on the Street," "The Mirror Poem," and "So Many Things."

Characters depicted include Big Bird, Count von Count, Cookie Monster, Betty Lou, Grover, Little Bird, Bert, Ernie. Sherlock Hemlock, Prairie Dawn, Barkley, Mr. Snuffleupagus, Farley, Herry Monster, and the Busby Twins.

A few illustrations of Big Bird and Little Bird in this book were reused in the adaptation of Everyone Makes Mistakes in Three Sesame Street Stories in 1985 (like this book, Everyone Makes Mistakes was also illustrated by A. Delaney).

This book was also recorded for the Big Bird StoryMagic toy in 1987.
