Fox-foxes inhabit the forests in the B3-B4 area. They resemble perfectly normal feral foxes. Also, they have two heads so are naturally twice as good.
For most of a fox-fox's life, the neural activity of both heads are synched and both sides are almost identical, baring perhaps a few minor personality quirks. After twenty or so years, the fox-foxes begin to experience what is known as Relationship Degradation. During the following years, the heads find their personalities diverging. Slowly at first, they begin arguing and generally find themselves able to stand each other less and less. Finally the Degradation boils to a point and the most pivotal moment of the fox-fox's life occurs: The Divorce. The two heads simply cannot stand each other any longer and decide to go their separate ways by pulling in opposite directions really hard, usually after a heated argument punctuated by screams of “It's over!” The fox-fox splits in two, and for a brief few days each “fox” is vulnerable as new limbs and finally a second head grows back in. Once the regeneration is complete, each new fox-fox finds they have a perfectly agreeable second head and are able to blissfully continue on with their lives.
While having two heads was wonderful in that the fox-foxes could do things like talk with one head while holding a hammer in the other's mouth, they did have a bit of trouble building things. And thus they discovered if they got really frustrated and sat down and fumed over it really hard, they could pick up and move things with their double-minds. Honing this skill, they became advanced in close-range telekinesis, which they called Looking at Things and Moving Them, and also things like shooting fireballs out of their mouths (called Shooting Fireballs Out of One or Both Mouths), because that's awesome.
