polar bears, bats and more

Polar bears getting distracted by raw fish on the floor, being this able to interrupt aggression the same way piglins get distracted by gold, eating it instead of checking it. Also polar bears may lose a nail when attacking a shield, may be used for a new banner pattern or to turn it into bone meal.

Bats react when they get close to a light source, emiting a sound that will alert/distract other mobs as if a player was on the same spot.

In cold biomes saturation is lost at a slightly higher rate, may be countered by eating stews (for a different amount of time based on the type of stew) and campfires (while being close to them there's no climatic effect on saturation). Easily solved by eating more with low to no penalty for the player. Is meant to be a fun and interesting way to exploit food types.

Same effect on saturation as the one above for deserts, countered by drinking any potion, stew, milk or water bottle (again the time it's countered varies) and shadow (no climatic effect while sunlight cant hit directly, as mobs when burn by it).
