- Inconsistent Dub: In the original German dub, Yoyo says that he is a hero of thousands adventures, always have. Doc Croc is described as scientist, nature reseacher and private learner.
- Keep Circulating the Tapes: In several countries, the show didn't get a full DVD release. There's GT Media's 2007 13-disc The Fairy Tales of the Brothers Grimm boxset of the episodes, but that's kinda it for a full series release in the States.
- No Export for You: Hasn't aired in many countries. While MainStreet Entertainment distributed the English dub in the United States, it was only available via an in-house children's cable on-demand service from Charter Communications over there.
- Despite that the first two seasons aired in Finland, third season never did. Then again there was a ten year gap between in second and the third season.
