The LET’S ROCK! Elmo is a rockin’ singing’ delight. Kids choose which instrument Elmo plays, and he magically recognizes which one you give him. Elmo can tell when you are playing the LET’S ROCK! Guitar, Keyboard or Microphone–and he plays along with you! You have to see it to believe it. Hasbro asked At Play to come up with a concept that will let consumers experience the LET’S ROCK! Elmo toy, pre-purchase. We created a virtual, interactive demo that mirrored the functionality of the toy along with a promotional video.
