A Sandbox for the purpose of Hetalia Cleanup, storing viable things that could be moved, rewritten, or applied tropes to.
- Hetalia was serialized in a seinen magazine (Comic Birz). Yes, the series known for its almost entirely female fandom can be called a seinen. World Stars also has the distinction of running on Shonen Jump's sister site Shonen Jump+, though there's less of a gap in Periphery Demographic in most works relating to that magazine.
- As an additional sidenote, said author was living in New York when he came up with the idea, which probably explains why it seems as though it's not quite expectedly Japanese.
- Switzerland and Liechtenstein view each other as "siblings" (wir sind bruder).
- For America's Maru Kaite Chikyuu they used the "Awesome" and "Music" straight from Lady Gaga's "Just Dance".
- In the ending song from the movie, you can also hear him yell Yes We Can! at one point.
- He explicitly says "Yes we can" in "WDC World Dancing", one of his character songs, too.
- In the ending song from the movie, you can also hear him yell Yes We Can! at one point.
- Romano/South Italy's character song actually uses the rhythm and tone of Tarantella Napolitana. Which makes sense given that when compared side by side, they sound exactly the same
.- Poland's Marukaite Chikyuu incorporates elements from the Polish National Anthem.
- In addition, it seems that Frontier Works did their work; you can sync-up both Poland and Lithuania's Marukaite Chikyuu, and Switzerland and Liechtenstein's Marukaite Chikyuu, so they sound somewhat like duets. Furthermore, within the recent World Twinkle character CDs, each character references the other character with whom they share a CD with. This is most prominent on Norway and Iceland's CD, where they call/receive a call from one another midway through their songs.
