big woods

One more thing: when Pig is in the woods and he doesn't get touched by trees, isn't it because he can hear them? He is using something like Sonar, and while I know that Horn can freely pass through the trees after he falls in the pit because he is one of them (He Pen Sheep calls him a "neighbor"), I thought that Pig could do so because of his sonar, possibly mechanical in nature. Was he that suprised? I need to look again. Marc Aramini
