With the Octo Shower in the rearview mirror, it’s time to focus on Cephalon HQ. The Octarians maintain a firm grip on this area—if the Great Zapfish and Callie are being held captive, they’ll be found here. Utilize the flying-saucer platforms to explore the surrounding area, seeking out the well-concealed Octarian lairs. You need to secure six more Zapfish before the area’s Boss Kettle opens, allowing you to finally uncover the truth. Sheldon supplies you with the Hero Brush here, completing the set of Hero weapons—feel free to replay previously completed lairs and boss fights with these weapons.
