[Zootopia directors on designing this scene]: It was just one of those things where, when we would talk about them finding the nighthowler flowers being distilled into a serum, we would just kind of add to the end of it, ‘Like Breaking Bad.” We’d say, ‘A lab…like Breaking Bad’ or ‘Blue flowers, like Breaking Bad.’ And little by little, it just became like Breaking Bad. At a certain point, the scene just wanted to be that scene, so we said, screw it, we’re just going to name these two characters Woolter and Jesse. Not Walter, but Woolter. For a ram.
