Описание сериии:
The citizens of Townsville panic over the appearance of black clouds over Townsville, but those clouds are yet rain clouds. The rain itself, however, is a problem, as it causes cities, objects, and clothing to erode into mush. The Professor explains to the Girls that this is because of tiny robots in the rain called nanobots which steal carbon from the environment. To make matters worse, the nanobots are eating everyone's clothes! After a failed attempt to stop the nanobots, the Girls use one of the Professor's inventions - the Micro-Stabilizer - to shrink down to the nanobots' size.
As the Girls take on the nanobots, the Professor attempts to direct the townspeople away from them. The nanobots step up on their resistance, focusing their attacks on the girls and combining into a 6-inch tall monobot. Though it overwhelms the Girls, the Professor is able to squash it flat, ending the invasion. The girls are credited for saving the day even though it was the Professor that squished the monobot
