With Play-a-Sound: Sesame Street, Ding Dong! Elmo's Here!, little readers can enjoy a Sesame Street adventure as they ring the doorbell again and again. Elmo and Abby have plans to gather up old stuff that people no longer want and give it to the Twiddlebugs to make into something new.

They go ringing the bells of famous characters from the classic TV show Sesame Street, including:
• The Count, who gives them some bouncy balls (and provides counting opportunities for toddlers)
• The Cookie Monster, who gives them a rubber band
• Bert, who gives them a propeller from a propeller hat
• Ernie, who gives them some dominoes
