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.
The Adventures of Jimmy Neutron: Boy Genius (2002)
1 continuity mistake in The N-Men
Starring: Rob Paulsen, Debi Derryberry, Jeffrey Garcia, Mark DeCarlo
Factual error: When the boys are sent back to the Cretaceous era, they come across a leptictidium, a small, bipedal mammal they call "Leppy." Leptictidium were not around in the cretaceous, they didn't appear until around ten million years after the dinosaurs went extinct, in the early Paleogene. They also lived in Europe, not North America.
Sheen: Jimmy, where's the bathroom? All I see is sand and I'm not a cat.
