Hunger

Creature Stage
The Hunger Bar is what tells you if your creature is hunger or not. The Hunger Bar is orange and is beneath your Creature's Health. This only appears in the Creature Stage. When the Hunger bar is low, your creature needs to eat something. Depending on your diet, (Herbivore, Carnivore, or Omnivore) your creature can eat Fruit, Meat, or both. Herbivores can eat Fruit. Fruit grows on large trees, or on small bushes. Carnivores can eat only meat. You must kill any creature for meat. Omnivores can eat just about anything. Eggs can be eaten regardless of your creature's diet type. However, this must be a last resort, because if you eat another creature's egg, they will get angry at you and attack. But eggs can also give a reasonable amount of bonus DNA Points. If your Creature's health bar goes down all the way, it will die of starvation.

Tribal Stage
The Hunger Bar in the square where your tribal members are pictured. Same goes for the Tribal Stage as is in the Creature Stage. You must bring back any food that has your Tribe's diet, and they will set it below their totem (if one). When the Tribal members are hungry, they will go to the food pile themselves, but you can direct them to the food pile yourself, by selecting the member/s you want, and right-clicking on the food pile.
