Professor Pig

The Professor Pig is an unplayable large pig that will appear in Angry Birds Toons. His first appearance may possibly be in "Massage Me".

Birdsonality
"The Professor Pig is an inventor. Inventive and imaginative, he has an infectious excitement about new things. This excitement lets him accomplish great projects if he really puts his heart in them. The details sometimes escape him, and he's not very accepting of piggies who don't share his vision. But he'll let other pigs sort out the details while he focuses on the big picture."
