The fin-kicking adventures continue! Dr. Paradigm is hiding out somewhere in Fission City! The Street Sharks may have stopped the mad scientist and his Seaviate goons, but they couldn?t capture him. Even with their arch-nemesis at large, they?ll have to stop their search when a new big-top circus mysteriously appears in the waterfront district. To the public, it seems like a regular, fun-loving circus. But the Sharks are hearing rumors about strange noises around the circus at night! Surely, this couldn?t possibly be connected to Dr. Paradigm?s latest schemes… right?!
