Ms. Mari's class is going on a field trip to the WaterWorks-main control center for all of the water systems in DenTech City. But there's a problem with the pipes! The nerdiest villain on the Net, BubbleMan, has an evil plan to turn every fixture in the city into a flooding fountain. A Dimensional Area forms around the WaterWorks and BubbleMan materializes to take control of the system. Lan and MegaMan CrossFuse to battle the bubbly bandito, but the power of the Fusion soon fails. Our heroes seem to have a problem communicating--and unless Lan and MegaMan can work together as a team, DenTech City is sunk!!
