Entre Riosball was born a 
7ball, as son to 
Argentinaball.
Currently it is calm but formerly was a revolutionary who fought alongside other balls (including 
Uruguayball and 
Rio Grande do Sulball) by a federal Argentina but failed in the attempt.
It has federation, liberty, and strength.
It is mainly about its nature and landscape (jungles, swamps, forests, and rivers). Its rival is -icon.png){kind=icon}
Santa Feball (Argentina) as they both have similar populations, climates and basically similar everything else.
