The Last, Fleischer, Betty Boop Cartoon where She appeared. Rhythm on the Reservation is an unfortunately crude attempt at humor involving Betty on an Indian reservation. The film is comprised almost entirely of a single musical number (a common trait of later Betty films) and features some ugly stereotypes of Native Americans. A final cartoon was released under the Betty Boop banner, but she did not appear.(http://leclisse.wordpress.com/2009/06/23/betty-boop-and-friends-1930-1939/
