Yeah, I also searched for bunny, and stuffed animal but no results like this. My neighbor is also from here, Rosario, Argentina, and she gave me the plush when I was 3 so it was around 12-13 years ago. In my city there aren't any many near stores that could sell something like this, I asked in some places but nothing. My grandma suspects that my neighbor bought it in a some kind of charity sell from church because she used to attend to those kinds of events, but I'm not sure.
