Animation errors are a phenomenon in cartoons, which means some scenes are weird, inconsistent, or even illogical. Sometimes these represented multiples of otherwise unique characters, characters appearing in inappropriate scenes (even after their original deaths in some cases), inexplicable deviations from character models, and odd size variations. They were most rampant in the original Generation 1 cartoon, due to the low animation budget. However, the cartoon was not alone in this respect considering the production values of most other cartoons in the 1980s. They should not be confused with palette swaps, which are for the most part intentional.
