Soul

The soul is located inside the body of every creature, and it is the creature. The soul controls the body of the creature. It is made out of magic. It looks like a floating mass of red fire.

Souls is like an humans brain's. Souls run on Magic Energy, I guess. And also, since they are made out of magic, they can do anything. Like explode your head. Or stop time. Ok well they can't stop time. But the reason that the talking dumb animal characters cannot explode your head is that they have to run consciousness.exe on every frame. Consciousness.exe takes up 95% of their CPU. The rest is reserved for output (a.k.a. speaking, movement, creation of a special blood plasma, e.t.c.). The rest are done by cells and stuff in the body. JUst like us.

However, they can still explode your head if they must. They just get a rocket launcher and shoot it at your head.

In a system (a.k.a. body (a.k.a. umm... full system?)), they get their source of Magic Energy from food. They convert the food to Magic Energy. Then the Magic Energy gets sent to the soul and then the soul does some stuff and also creates some Magic Energy. The outputted Magic Energy will always be less than the inputted Magic Energy because of the laws of thermodynamics or something.

Only the talking dumb animal characters have souls.
