I finally found a voice actor who I might let voice act Slovakia (Czechiaball's brother) and Hungary!

It's...

Hexamak!

He's a year older than me but he sounds like a perfect voice actor, as it says he voice acts..

Who else will voice the female Countryballs?

Hopefully not me, I'm 14 and I don't have that much of a high kid voice anymore, so I'll let an actual real life female person voice them!
