The cell's eating habits in the Cell Stage directly influence its diet in the Creature Stage, and only mouths appropriate to the diet (Herbivore, Carnivore, or Omnivore) established in the Cell Stage will become available in the Creature Stage. Once the creature grows a brain and the player decides to progress to the next stage, the creature editor appears, prompting the user to add legs before the shift to land. The Creature editor differs in that it gives the player the ability to make major changes to the creature's body shape and length, and place parts in three-dimensional space instead of a top-down view as in the Cell editor.
