The stalwart heroes of the Zula Patrol are on an expedition collecting samples of weather for scientist Multo's research -- using their loyal pet Gorga's ability to collect and bottle all kinds of weather. But when the Zula gang inadvertently hurts Gorga's feelings, he decides to leave Zula and find another planet to live on. Interplanetary villain Dark Truder then tricks Gorga into stealing the weather from other planets - part of his latest nefarious scheme to rule the Universe. The ZPers find out and go after him - in the process learning all about weather, both terrestrial and interplanetary.
