n play and sing 6 laugh-and-learn tunes while their friend Elmo teaches them all about using the potty. The interactive buttons play 6 familiar melodies, including "If You're Happy and You Know It," "I've Been Working on the Railroad," "Someone's in the Kitchen with Dinah," "Pop! Goes the Weasel," "Row, Row, Row Your Boat," and "Boom, Boom, Ain't It Great?", with playfully updated song lyrics that take the reader through the whole potty experience, from the first "gotta go" moment to celebrating success! Music and singing help build language and literacy skills, and custom lyrics to familiar songs help children learn and remember new routines.
