Walruses in the game would be a good food source for Polar Bears specifically, all other mobs with be killed within 1 hit from the tusks with a bleeding effect after they get stabbed and flee, wolves would attack in packs but after a member is injured they'd leave, also seals would be nice as a safe food source for all other animals because they are defenseless and they'd run away, they would be tameable.
Sorry but this is a badly put together idea. Animals don't need to be added just for the sake of being a food source. The game has more than enough food and slapping in animals for just that reason is bad game design. Seals are defenseless but they're tameable? Uhhhh okay..? We don't really need more tameable animals either. The bleeding effect is also super random. If a tusk causes bleeding, then other sources of damage should also cause it.
