Continuity mistake: When Jimmy is in his lab, in the shot where the camera zooms into his eye, in the shot just before that shot, notice the digital clock on Jimmy's counter. The seconds part jumps from the 30's to the 40's twice in two different shots.

1 continuity mistake in The N-Men - chronological order
Starring: Rob Paulsen, Debi Derryberry, Jeffrey Garcia, Mark DeCarlo
The League of Villains - S3-E16
Factual error: As the villains are approaching to Earth, South America is shown just under Asia, connected to the Arabian Peninsula and the southern tip of India. The two continents are nowhere near enough to each other to be seen at the same time from space, much less connected. They are on opposite sides of the Pacific ocean, over 10,000 miles (16,000 km) apart. (00:06:45)
Sheen: Jimmy, where's the bathroom? All I see is sand and I'm not a cat.
Who Framed Jimmy Neutron?/Flippy - S3-E14
Trivia: The theme song during the title screen and throughout the episode "Who Framed Jimmy Neutron" sounds similar to the theme song for the show "Cops".
