Forgive me, I had to.
Added
I've added "mana" to the world and an creature type that lives off of it. Creature 04 will only pursue items that possess mana. When 04 collects enough mana, it grows into creature 05. Unlike 03, 05 changes forms after collecting more mana, then changes back, A 04 will breaks off when this happens.
Changed
I've changed how creatures categorize their food. This still needs more work, though. I've also changed how 02 becomes 03. To account for the new diet, 02 is no longer on a timer, now just growing with enough mass.
Plans
I'm going to work on how they choose there food and try to fix an issue that keeps adding mass and mana into the system over time. I also have one more creature type that will interact will both mass and mana, just need to work out some of the concept before I start programming.
