- The last two episodes of the series, "April Fool's Day" and "The Journal", were produced in 2001, a year after the rest of the season and the movie. This is because episodes 98-100 were originally going to be the three half-hours of the TV movie Arnold Saves the Neighborhood; but when the TV movie was selected for a theatrical release under the title of Hey Arnold! The Movie, Nickelodeon ordered three more half-hours to fill in the gap in the production schedule, which were turned into these two episodes.
- As a result of being produced separately at a later date, these two episodes share a few differences with the rest of the episodes of the season; namely featuring Alex D. Linz as the voice of Arnold, improved animation quality, and a different tone of yellow for the title and opening credits.
- Season 5 consists of 20 half-hours, but a total of 24 were aired in the US as part of the season. This is because three episodes from Season 4 (75, 77 and 80) and one episode from Season 3 (Parents Day) were held over for unknown reasons.
- While in many other countries the season (and the series) finished airing in 2002, the U.S. broadcast was very erratic, taking almost four years to air every episode.
- Despite "The Journal" being the last episode in production and chronological order, it wasn't the last episode aired in the U.S.
