Grizzly Bear in Forests

Grizzly bears could be found in forest biomes, it would be a neutral mob who only attack when provoked, that being running towards them with a weapon, going near them and hitting them, they would also make all other bears hostile too.

you can befriend them by feeding them fish and honey at the same time, although they wouldn't leave their family/home, trying to lead or do the previous things will make them hostile against you.

they would have 40 hearts and deal 8 hearts without armour

they would also hibernate through the minecraft days and shed their fur, waking a sleeping bear would make them hostile and their fur could be made into the bear helmet which scares away hostile mobs
