Episodes

Pilots (1998 and 2001)

Title	Directed by	Written by	Original air date

"Jimmy Neutron: Boy Genius"	John A. Davis	John A. Davis, Steve Oedekerk, J. David Stem and David N. Weiss Story by: John A. Davis and Steve Oedekerk	December 21, 2001 (2001-12-21)
An extremely intelligent ten-year-old boy and his friends must rescue their parents after they are abducted by aliens.

Interstitial Shorts (2000–2001)

These shorts were used to promote the film, later being released on the DVD. All of the inventions in each short were seen again at some point on the television series (except for the Pain-Transference helmet). Clips from similar versions of these shorts, along with clips from the 1998 pilot, appeared in the teaser trailer for Jimmy Neutron: Boy Genius. The biggest difference between the clips seen in the trailer and the original shorts is that Jimmy wears the white and red striped shirt he wore in the pilot, rather than his trademark atom shirt.

"Carl Squared" Carl asks Jimmy lots of questions when he clones himself. The cloning machine is seen again in "Send in the Clones" and "The Trouble with Clones".

"Calling All Aliens" (Parts 1–5) Jimmy receives a message, thinking that it is from aliens. But when he says "school Goddard", he gets teleported to school. He tries several attempts to try to communicate with the aliens. Aliens are also mentioned in Jimmy Neutron: Boy Genius. It serves as the prologue to the movie.

"Cookie Time" Jimmy has a remote control that controls time. He asks his mom for a cookie and gets it. He keeps rewinding but Goddard bites the remote and sends them back to the prehistoric era. The remote is seen again in "Sorry, Wrong Era".

"Hyper Corn" Jimmy invents his HyperCube, to store infinite items in one small place. But, it is dinner time and they are having creamed corn, which Jimmy hides in his Hyper Cube. After Jimmy's dad thinks it is a brain teaser puzzle and breaks it, Jimmy finds out that he likes it after all. The Hyper Cube makes appearances in the episodes "Hypno Birthday to You" and "Holly Jolly Jimmy", although it looks different from in the original short.

"New Dog, Old Tricks" Jimmy introduces his robotic dog, Goddard, to Cindy and her dog, Humphrey, who Cindy says is the best dog in Retroville. However, after showing each other new tricks, Goddard wins the argument. Humphrey makes brief cameos in other episodes. Note: A clip from a slightly different version of this short appeared in the original theatrical trailer for Jimmy Neutron: Boy Genius. This version ends with Goddard putting himself back together after Jimmy says, "I can fix that."

"Pain Pain Go Away" Jimmy visits Dr. Pane, the dentist, using his Pain-Transference Helmet to transfer the pain to Cindy. He gets in trouble, though, when Cindy snatches the helmet the next day and retaliates by injuring herself and sending the pain to Jimmy.

"Sea Minus" Jimmy accidentally uses his Matter Transporter to move the Neutron's House underwater! The Matter Transporter is seen again in "My Son, the Hamster".

"Ultralord vs. The Squirrels" Sheen gets his new Ultralord Action Figure in a tree. Jimmy must get it back with his Hypno Ray invention to keep it away from the squirrels. The Hypno Ray is seen again in "Hypno Birthday to You". Note: A clip from a slightly different version of this short appeared in the original theatrical trailer for Jimmy Neutron: Boy Genius. In the trailer version, the scenes take place in the park, rather than in Jimmy's backyard, while Sheen is replaced by Nick Dean.

Season 1 (2002–03)

Unlike Season 2 or 3, Season 1 of Jimmy Neutron takes a more comical approach to the show, with little development of Jimmy and Cindy's relationship.
