Get ready for a fun letter ride! When their firefly friend, Edison, takes Tad, Lily and Scout to the place of his childhood dreams, the gang is shocked to discover that Alistair Alphabelly's Amazing Amusement Park is... closed! To make matters worse, Edison has gotten himself stuck atop the Fantastical Ferris Wheel. The only way to save him is to turn on the rides in the park with the magic of the alphabet. Now the children must learn all of the letters, big and small, to save their friend, save the day and perhaps even meet the rhyme master himself, Alistair Alphabelly!
