Adored by the Network: Despite being moderately popular at best when it first aired, Nickelodeon pushed it as one of their most valuable commodities, airing it any time they could and even greenlighting two theatrical movies, both of which underperformed.
Screwed by the Network: The series had a two-episode grand finale, but the second part wasn't aired until over a year after the first one. When they did air the actual last episode, it was without much advertisement and most viewers weren't aware of it.
What Could Have Been: Originally, the show was be more along the lines of an "educational show" centering around Nigel traveling around the world and teaching people about the various animals that lived there. Nickelodeon decided to change it into a Doctor Dolittle-esque adventure, feeling it would be more successful with a child protagonist.
