The tigger uses a arm lock on the kids elbow, most untrained people do not know how to do that, if the tigger had wrestling or something like that in highschool then his training stuck with him.

Now at first i thought that the tigger was locking the arm on purpose to strike the kid, his lock was pretty good.

But i look again and i see the kid seems to have a smirk, and the kids first hit the tigger aswell.

Score one for tigger superb use of the an arm elbow manipulation, and possibly blind left hook!
