Bad Barney returned in Episode 0723, having not changed for the better. He prods and mocks Big Bird into doing something bad himself - stealing a zucchini from Mr. Macintosh's cart. Barney makes his situation worse by blackmailing him into making him dinner, doing his homework, and other deeds. Big Bird confesses on his own and Barney flees when he hears he's been ratted out.
