For those craving something more lighthearted without the wild insane world saving stuff, and who want cute and funny adventures with the personified versions of the worlds countries.
I'm not sure what would happen but the various countries and maybe some smaller ones who weren't in the series would be together going on insane adventures and other things
I have personally really been wanting to see interactions between Puerto Rico and America (Since I grew up in Puerto Rico for several years and even speak Spanish fluently) as she is older than him and yet technically he treats her like a younger sister.
So...I don't know. Anyone want to join up and engage in endless hi jinks of the countries running around the world, maybe fighting aliens or some other evil with their insane ways.
*Also for those who don't know Puerto Rico is a commonwealth of the US, so its part of the US, its people are citizens and people from the mainland can get over there and live there.
