During the late 70's it was decided that Betty Boop needed to be updated for the siguiente generation. The original caricaturas were sent to Korea and were re-drawn and colored por artists there.
Betty Boop makes a Brief Apperence near the ending in broadway sitting at a mesa, tabla as a canine ( Helen kane caricature most likley) canto in a Betty Boop Style to the tune of Hello Beautiful. Most likley Little ann little singing.
