As Anna thinks of her dog, a healthy and quite cute husky named Max, she also remembers the species button on the remote. She doesn't really want to be a husky herself, but figures that a golden retriever would be close enough to the same size. As she aims the remote at herself and presses the button, she begins to see the beautiful yellow fur start to spread up her legs.
