 Annie and the team are in hilly San Fransisco today to try out Annie s new toy - an adorable little Purple Plane. Amazingly, the toy plane is powered by Annie s singing voice. When Annie sings high, the little plane can fly up into the air! Just then, the team hears a toy Green Helicopter who is in terrible trouble. The helicopter is stuck wayyy at the top of the tallest Redwood Tree. That s very high! But Annie s little toy plane is bravely determined to try and save his friend. On this mission, Annie must sing Purple Plane over taller and taller obstacles such as Coit Tower and the Golden Gate Bridge. With the audience s help, Annie must sing Purple Plane higher than she has ever sung her before, soaring high enough to save Green Helicopter at last.
