She was fearless compared to her timid self last year. Once she felt comfortable, she was running up and down the pens giggling in delight. She was so proud of her light shoes that she wanted to show them off to the pigs, who in turn were petrified of the flashing lights she produced as she stomped up and down.
The only time the pigs weren't afraid of her shoes was when she was sitting still. In that scenario, they were more interested in trying to get a taste of them, which is the cause for this stiff "cheese' picture :)
