On their way to Rainbow’s Edge to seek the help of the Ray Keepers,
Professor Plano, Zed and Zee meet a flight of sickly, grey dragons.
They’re all caught up using their Bottle-Bottle screens that give off a
strange, eerie glow. Lord Myopic must be up to no good again! The trio
rush to find the Ray Keepers to save the dragons, but are they too late.
