Back in the late 19th and early 20th century there was a movement towards the occult. Secretive organizations or orders devoted the hidden or forbidden knowledge. Today, people try to find any reason to connect Masons and other societies to politicians, performers and anyone else in the spot light. This tradition of lampooning fringe groups has been around longer than Scientology. There were three things that stuck me upon watching Bimbo's Initiation: a distinct reference to the Hermetic Order of the Golden Dawn, traps that made this animation into a proto-Saw, and the use of sex-appeal to get Bimbo to join.
The Hermetic Order of the Golden Dawn, or Golden Dawn was a group that practiced Theurgy, or the use of rituals with the intent of invoking the will or presence of a higher being. Of course this mode of worship has been around longer than the order. Towards the 1930's and 40's the Golden Dawn were in decline and were an easy target for the times.
I found the traps that kept Bimbo in this cult's lair fantastic and flowed into each other perfectly. All were very devious and used Bimbo's actions against him. It seemed that he could keep on getting away from this torment until the cult used a honey pot to lure him into recruitment. Although, this lead to the non sequitur of a room full of Betty Boops and mutual spanking. At least everyone seemed happy.
