Axel and his toys deploy the Joyride in a "ship" to "ship" battle against Dr. Nautilus, who has punctured a water main to flood the sewers and established himself as "Admiral Nautilus."

Zoe leaves Axel in charge of a school project to watch over an infant simulator doll; when MadCap brings the doll to life, Axel and the team must stop the baby without damaging it or risk getting a failing grade.
