Elmo's Play Day features a book with a three-trigger sound module whose sound buttons correspond to icons in the text. The book comes in a decorated box with a plush Elmo. The story features Elmo on his search for a playmate on Sesame Street. All his friends are busy, until he finds Zoe. The two blow bubbles together. Icons in the spreads match triggers on the module that produce sounds. The sound element of this book enhances the reading experience, drawing in the sense of hearing and providing hints to the meaning of the words in the text. The sound buttons also exercise hand-eye coordination and matching skills. Trigger sounds include the sound of blowing bubbles, the musical sound effect of Elmo skipping along the street, and the silly sound of Oscar's trash can.
