The story follows Elmo and his friends as they go on a fun-filled adventure, collecting letters and learning about the alphabet. Along the way, they encounter various characters from Sesame Street who guide them through different settings, such as outer space and underwater worlds. The ultimate goal is to help young children develop their reading skills by associating written letters with their spoken forms.
The gameplay is designed for preschoolers, with simple controls that allow players to navigate Elmo through various mini-games. The player's objective is to collect assigned letters in each level, which are then uttered by Sesame Street characters, reinforcing the connection between written and spoken forms of each letter.
