Betty Bluff's debut was in Doug Wears Tights, where she runs the Bluffington Ballet and uses this to Beebe's advantage to get her the lead role in The Beetcracker. After Beebe bombs her audition, she blames Doug for ruining her daughter's audition, but Beebe dismisses that accusation when she admits to doing it herself. She wanted to be costume designer, rather than be involved with performance and that Betty "wanted it for her". After realizing her mistake, Betty apologizes to both Beebe and Doug.
Like the rest of the Bluff family, Betty is not above using her status and influence to get her way, specially when it involves her daughter. She's very snobby, condescending, and rude to almost everyone.
