My Little Pony - Sing and Play - Follow The Lights Piano Songbook (2005)

"This wonderful book has a working piano that plays 12 favorite children's songs with a My Little Pony twist!

Your child can play the songs by following the notes on the page, or you can set the piano to light up each key so little fingers can follow along, or sing along with the "piano player" feature! Read the words or sing the songs - this is a book that can grow with your child and encourage the love of music that will last a lifetime!"

Needs new batteries, 

Never been used before though.
