Halloween Talk

As I'm reading the blogs I follow I can't help but think about what Baby Bo will be next year for Halloween. I love dressing up for Halloween, but this year I just didn't feel it.
I have always loved this McCall's pattern, and I would love for Baby Bo to be an elephant next year. Bo likes this costume also, but he is really indifferent since it is a year away. Now, if only I can convince my mom to help me make it. She is the best costume maker.
Has anyone made this pattern? If so was it very hard?
