Fair for Its Day: The Chinese Conjurer and Tiger Lily are pretty broad stereotypes by modern standards, but they were fairly progressive for the time by being friends to Rupert instead of Yellow Peril villains. They have also always been drawn in realistic style, without the gross racial caricatures seen in some other contemporary works.

Popular with Furries: The show has been known to have been a major closet key into the fandom for those who grew up with it.
Sweet Dreams Fuel: It's an incredibly calming, cozy show where the adventures are never too tense for viewers.
is pretty catchy.
