Professor Eugenius finds both his career and secret friendship with the Fixies in danger when his college sweetheart, Erica, threatens to reveal that Eugenius only beat her out of the University’s Grand Prize in 3D Printing because Fixies were secretly helping him. Erica challenges Eugenius to a rematch to show the world who the better inventor really is! Eugenius will employ his Fixie friends while Erica has little helpers of her own — crabbots, miniature robotic crabs that are faster and stronger than the Fixies.
