On her first day of high school, Jenny seeks to make some new friends, and she thinks she can find some in the arrogant Brit and Tiff Crust. Unfortunately, the Crust cousins do not share the same feelings and plan to humiliate her.

Jenny wants to get ear piercings, but her mother refuses to give her ears. Sheldon offers to step in and help, but the ears he builds end up being disproportionately large on Jenny's head.

After being lectured about planned obsolescence by Brad, and later finding herself unable to defeat the energy vampire Gigawatt, Jenny fears being rendered an obsolete robot. Determined to beat Gigawatt, she soon tries to "upgrade" herself to make up for her weaknesses against Gigawatt.

Jenny's new boyfriend, a male robot named Kenny built by Dr. Wakeman's rival Dr. Mogg (who copies many of Dr. Wakeman's inventions while adding distinctive twists), seems to be the perfect match for her at first; however, Kenny soon starts to display oddly dog-like characteristics. Meanwhile, the new couple attracts Sheldon's jealousy.
