Kai is 4 now! Slightly updated ref for that. c: He now only wears his bandana about 70% of the time, rather than 100%, because he seems to think it's "not cool" for someone his age. Oh well, I guess he's just growing up.
And he's got quite the funny thing going on with his... bangs, I guess you call them. x3 Nobody's sure if it just grows that way or he's been sneaking Michelle's hair gel.
Oh, and he is bulldog sized, very large for such a young child.

EDIT [11-2-2013] (8 years old): He's completely given up his bandana now in favor of two silver studs and two silver tail rings.
