Mobs
Wooly cows can be sheared for uniquely patterned wool or milked for fresh milk. They naturally spawn in various variants: Umbra, Beige, and Warped.
Warped wooly cows, with their distinct appearance, emerge near lit nether portals within the warped forests of the Nether, mirroring the spawn behavior of zombie piglins in the Overworld.
Bears have a chance to spawn in all types of forests.
Generally, they are peaceful animals. However, if they have babies with them and you approach them, there is a chance they will attack you.
Note: Those are Bears. You can't tame them!
