Birdsonality
"The Professor Pig is an inventor. Inventive and imaginative, he have an infectious excitement about new things. This excitement lets you accomplish great projects if he really put your heart in them. True, the details sometimes escape him, and his not very accepting of people who don't share his vision. But hey, let other people sort out the details - he'll focus on the big picture."
