Dancing Bear - What is that on the left?

There is a bright spot that moves around to the left of the bear. There is even a shadowy shift below the bright spot. Is that a body?


Some one with mad skills could make this phenomena much more clear and visible than what I can do. Pay close attention to these times: 20 to 24, 27 to 28, 31 to 34 and 1:01 to 1:04
