Dango lives in Japan, so he's not likely to know any of my other characters canonically. Unless they were to take a trip abroad, in which case who knows?~

For fun he enjoys doing stuff like taking naps, stuffing his face (he's technically a guardian spirit of a sort so he does get offerings), and taking warm baths. Admittedly that last one is especially so because he enjoys soaking his "package" for a good while...
