Were there two squirrels?
It seems to me they used two squirrels in this film. I mean, one seemed to be a trained squirrel who could do all sorts of tricks. But I think he was sick or something, because he looked kinda ratty and seemed to move real jerky and stuff- like he had arthritis. And the other squirrel was younger and healthier and moved real natural, but he didn't know any tricks so they used him when they needed a squirrel to run around in the rafters and stuff..
