Bad Export for You: The South American versions of the toys are bowdlerized to the point where the good doctor herself is Ambiguously Brown or outright white in those markets. This has led to fans from those countries buying the toys from North America just because they are colored correctly.
Keep Circulating the Tapes: The show only had one DVD release in the entire year it's been out, and while Amazon, Netflix and iTunes stock the full season, those are generally No Export for You cases to the remaining 66% of the world that Apple et. al. deems undeserving to buy the series off them. However, the trope has been averted in that so far there have been no way to get even one episode in full off youtube due to Disney's iron fist in copyrights. Yes, it's still airing on Disney Junior, but even that it remains a pain to those who cannot get/don't want to get Disney Junior for whatever reason.note For example, in some countries, the local laws permits a Pay TV provider to exclusively monopolize a channel so they're the only provider with the channel, effectively denying subscribers of competing systems access to the channel, with no antitrust and anti-competition penalties from the government. This makes it a burden for those who subscribe to the competition but still want that channel.
Name's the Same: One of the episode is titled Dark Knight. No, a Batman action figure isn't appearing as the patient in the episode.
No Export for You: The toys are generally this outside of the Americas. They're practically nonexistent in many parts of Europe and Asia (save for a few areas with a healthy parallel import market like Hong Kong, Singapore, Australia and the United Kingdom).
Shout Out: The names of the Walkie Talkies in Walkie-Talkie Time were probably not chosen at random. Googling "Walter and Gracie" can bring up some fascinating results.
Retroactive Recognition: Actually, Lambie is this as she sounds nothing like Puppy Clifford, and the revelation only hits when fans scrutinize the credits and put the puzzle together using Google.
