The new, 300-story office building Megakat Towers is open for business, and Mayor Manx is trying to persuade foreign investor Mr. Young to house his corporate headquarters there. But Dr. Viper is back and he ruins Manx's plans as he seizes control of the tower with his army of acid-spitting ""plantimals."" He places a huge spore pod on the roof: when it explodes, it will shower Megakat City with spores, turning the metropolis into one big swamp (""Megaswamp City""). Obviously the Swat Kats won't allow this. While T-Bone runs interference in the Turbokat, Razor sneaks inside the building to stop Viper with the help of Callie Briggs, who happened to be inside when the building was taken.
