The first pic is closer because Dango is larger, too. Admittedly, I might have paid a little more attention. These static shots are supposed to all be the same sizes. Heh heh. But, I don't know why I didn't go over him again with the paint...
He's just waiting for the hamster to get off the wheel, then the hamster gets tired and stops, the dango is happy, the hamster freaks out and starts running again, and Dango is happy because he is being amused. It's like a game, I guess.
