WHERE DID ALL THE WATER GO? - When Bula reads about a "vanishing lake" in Zula's tabloid newspaper, Zeeter is skeptical. They go to investigate and find out the lake is hoax perpetrated by the nefarious villain, Dark Truder, whose ultimate goal is to make all the water of Zula disappear by vaporizing it. He traps Multo, Bula and Zeeter, but they manage to escape, thanks to their knowledge of evaporation and vaporization. They're too late to stop Dark Truder's wicked plan, but the joke is on Truder - when he learns the hard way that vaporized water turns to rain. THE DEW DROPS - The Zula Patrol learns all about condensation when they meet the Dew Drops, three drops of water who sing like a 50's Doo-Wop group. The Dew Drops need the Zula Patrol's help to enter a Battle of the Bands contest. Our heroes discover that Dark Truder has a condensation-singing group of his own, and will stop at nothing to make the Dew Drops lose! Using what they've learned about condensation, Wizzy & Wigg and the Zula Patrol save the Dew Drops and foil Truder's plans!
