Things have been mysteriously disappearing underground, making Johnny and Dukey believe that the people behind this are "mole people". When Johnny accidentally loses his dad's new camera, he must journey to the center of the earth to retrieve it before dinnertime, or he will be grounded.

Johnny uses his game controller to control people, but Hugh gets his hands on it and begins affecting Johnny in the process.

Johnny uses a bionic arm to magnify his arm strength to beat Sissy at dodge ball. However, it breaks after being exposed to cereal.
