Walter Bunny is Lola's loving, protective, and caring father. He is a popular and beloved member of the Royal Oaks Glen Oaks Oakwood Oaks Country Club, or the R.O.G.O.O.O.C.C. for short. His membership number is 16-73. In the episode "Father Figures", he was Bugs' father figure so that they could bond more as " father & son."
Walter dislikes Daffy because he used his membership number to get whatever he wanted from the club. He only lost respect for Bugs for one episode because he wasn't himself at the time. He went back to liking Bugs as soon as he got his old identity back.
