The player may feed the Mammoth, then Mammoth becomes happy and willing to help the player. If the player has something Mammoth may eat, Mammoth will sense it due to their strong sense of smell. If the Player rejects to feed the Mammoth, Mammoth becomes very angry and willing to do everything to get food. Mammoth could even attempt to attack the Player to get what it wants.
