root was an accident by a soda company who was trying to make a new kind of soda, instead of making a new drink they made a sentient slime monster with the mental capacity of a 3 year old, they tried to contain it fearing it was a horrible monster but when they finally caught it they found it playing with children, letting them use its slime like modeling clay, it didn't seem to have a hostile nature to it and seemed rather docile, and against the orders of their boss they let the creature loose in the world.
