"When Pants Attack" is the first episode of The Adventures of Jimmy Neutron: Boy Genius.


Jimmy, Sheen, Carl, and Cindy are attacked by their own pants when a new invention of Jimmy's goes awry, eventually setting off a chain reaction for all of the other pants in town. Now, they must stop Jimmy's pants before they take over the world. 


  • Jimmy's voice becomes deeper and more clear starting with this episode.
  • Cindy now wears a green tank top and khaki pants and has a single ponytail and Jimmy now wears jeans and sneakers.
  • "Go Jimmy Jimmy" from the movie plays in this episode.
  • The factory gender error Ultra Lord is meant to be a reference to when Barbie and GI Joe voice chips got mixed up.
  • This is the only time in the series where Sheen's mom is mentioned (unless one also counts the movie's PC video game adaptation).
  • Oddly, the promotional artwork for the episode shown here was used as the cover for the movie's score album.
