Jimmy and Timmy fight over who get's to take Cindy to the Friday the 13th Dance. But, when Professor Calamitous follows Jimmy to the FOP universe, Anti-Cosmo gets him to help his anti-fairy friends escape their prison (which cannot be penetrated by anyone from their universe). Now, the anti-faires plan to halt the Earth's rotation to make it Friday the 13th forever. But the problems had just begun. In an effort to impress Cindy, Timmy uses AJ's Gene Splicing Ray Gun and fuses Jorgen von Strangle and Calamitous together. With Jorgen's powers at his command, Calamitous can finally take over the world and do away with both Jimmy Neutron and Timmy Turner once and for all! Inventions: Portal, freeze ray, net attachment for hyper-cube, sound wave detector.
