Kai has developed not just an array of sounds that range from "dah-dah-dah" to "num-num-num" but a talent for creating chaos where calm and serenity once existed. He is entropy made incarnate. All human attempts at control and order are torn asunder before him. A box full of little toys - is merely a toy of little boxes to him.
He shows some selectivity when it comes to putting things into his mouth, but he still likes a good gnaw and nibble on something unfamiliar. Like my fingers.
