Let's face it, as entertaining as they are, the Mario cartoons were not high-budget productions. There are - dare I say it - errors! Whether a character is colored incorrectly, someone's voice is simply wrong, or one plotline is entirely inconsistent with another, there are things in these cartoons that are just not right. And some of them, really, are quite odd.

This subsection will include those weird incidents that have been spotted in the Mario cartoons. The Oddities are arranged first by series, and then by episode. Go take a look at what the cartoonists missed!

Did you spot something weird in the cartoons that is not found on this page? Email me! Credit for the idea for this subsection goes to ShotNtheDark. And that's no glitch.
