The team is at San Francisco, California and Annie has a small plane and calls her Purple Plane, which flies higher when she sings higher. They start to sing low and every time Annie raises her voice (in a glissando) and her hands, Purple Plane flies higher and higher. In the meantime, they see a green helicopter stuck on top on the tallest redwood tree. It is up to the team and Purple Plane to fly over the highest landmarks and rescue Green Helicopter before he falls down.
