Errors

Errors are a species on Earth. They resemble giant red letters, and are harmless unless "they get near your computer". They are often static, and usually stay in packs.

They are native to an unnamed desert (likely New Mexico or Egypt) that Indiana Jones visited.

Trivia

 * Papa Acachalla has a pet error.
 * One town (I think from the Attack on Titan video?) has a field of errors.
 * As seen in the Source Elevator videos, there was a spaceship filled with errors. This suggests that space travelers smuggle errors for some reason, or that they are more intelligent than humans may think.
