Jimmy Neutron: Boy Genius

Eleven-year-old Jimmy Neutron, a boy genius, lives in the colorful town of Retroville. He is supported by his loving parents, Judy and Hugh, alongside his robot dog, Goddard.

Jimmy undertakes an ambitious project to launch a communications satellite aimed at connecting with extraterrestrial beings. However, his rocket launch goes awry, crashing and causing chaos at home, which upsets his mother.

Excitement builds among the children for the grand opening of Retroland, a new amusement park. However, Jimmy finds himself grounded by his mother after a mishap with his jetpack, thwarting his initial plans.

Determined to join his friends at Retroland, Jimmy devises a clever plan using his shrink ray. This leads to an adventurous night filled with fun, as the kids sneak out under the cover of darkness.

Unbeknownst to the children, Jimmy's satellite message has inadvertently attracted the attention of the Yolkians, egg-shaped aliens from Yolkus. Their leader, King Goobot, spies a photo of Jimmy's parents, setting off a chain of events.

The Yolkians invade Earth and abduct all the adults in Retroville, leaving only Jimmy's teacher, Miss Fowl, who shrinks due to one of Jimmy's inventions. This causes initial chaos among the children, who are elated by their newfound freedom.

After some initial celebration, the children quickly miss their parents and realize they need to rescue them. Jimmy rallies his friends, outlining a plan to construct rocket ships using the attractions at Retroland.

The team embarks on their journey to the planet Yolkus, navigating through dangerous meteor showers. They cleverly camp on an asteroid, showing their resourcefulness and determination to rescue their families.

Upon arriving at Yolkus, Jimmy and his friends discover that their parents are under the control of mind-control helmets. Faced with this daunting realization, they must concoct a plan to save them from the Yolkians' sinister clutches.

Jimmy gets captured by Goobot, who reveals that Jimmy's satellite communication led them to Earth for a sacrificial plot involving their god, Poultra. Jimmy feels hopeless but rallies for an escape with the help of his friends.

As Jimmy is imprisoned with the other children, Cindy reminds him of his importance as a leader. Together, they devise a clever plan using a cellphone to contact Goddard, who comes to their rescue.

In a dramatic showdown at the Yolkians' Colosseum, Poultra, a massive alien chicken, is set to make an appearance. As tensions rise, Jimmy leads the revolt against the guards while Sheen makes a risky move to retrieve an escape vessel.

The group manages to escape Yolkus, but they are pursued by Goobot's fleet. Jimmy uses his shrink ray to grow to enormous size to confront Goobot, ultimately destroying his ship and securing their safety.

Back on Earth, Jimmy has a heartfelt reunion with his parents, where he realizes the importance of love and support in addition to intelligence. This moment solidifies their bond after the chaotic adventure.

In a whimsical mid-credits scene, a miniature Miss Fowl rides on an apple worm named Mr. Wiggles, heading to the cafeteria. This charming moment ensures that the spirit of Retroland lives on even after their grand adventure.
