- Author Existence Failure: Averted: Charlier did his best to continue the series after Hubinon and then Jijé's death. After the death of Charlier himself, the series was continued by other writers.

- Keep Circulating the Tapes: Episodes of the late '90s cartoon (in English, at least) are very hard to find online, and it never saw release on home video in North America.
