I've mentioned before that 9 is more brawny and Chani is more agile. What I didn't mention is that 9 has some serious jumping ability. These pics are from a set where he was jumping up after the Evil Feather Toy II. 
He's jumping about 2 feet in the air. In some of the shots, because of the perspective and the general neutrality of our apartment, it's hard to see how high he can get. 
Fortunately, Chris' pj bottoms provide a little bit of contrast, so you can see some of the height 9 can achieve.
