Fatou is super-hot as she vacuums the ground in front of Roger’s place. She asks him if he can invent an object to cool her down. Roger locks himself up in his saucer and comes out with a triumphant smile on his face. He has invented the portable Vaporonimbus, an artificial cloud that hovers above your head and gives off a fine and refreshing rain shower. Fatou is in seventh heaven, the cloud follows her wherever she goes but soon enough, she gets tired of being wet all the time. She asks Roger to turn it off. Argh!, no-can-do! The remote control no longer works. Roger decides to get rid of the cloud by creating an artificial storm. But the opposite happens. The portable cloud gets even bigger and starts looking mighty threatening. Danger is brewing! No probs, Roger decides to fly over the cloud in an airplane and neutralize it. Catastrophe! The cloud swallows the plane whole. Ah, luckily Fatou remembers she has a powerful vacuum cleaner at hand...
