Basically rescue the idea of this old mod that added them and Pandas to up to 1.12.2.
Of course, Pandas and Polar bears were already added by Mojang, so Grizzly and Black bears are the main target here.
Since i'm not from the lands these giants are native to, i'm not totally sure in what kind of biomes they would spawn, let alone how they could differ from vanilla polar bears. But i bet grizzly bears would spend time on rivers catching salmon, right?
