HR Giger: Passage Temple Life

a) On September 20th 2017, I looked back at a twitter post from 23rd September 2015  by the film director Guillermo Del Toro which presented a picture by an artist Lee Brown Coye saying "Seek him and enjoy the shivers". 

I looked for more images and found this certain one featuring what looked like a skinned lemur with sticks.

b) Far right sticks transform into tendrils hanging from the seated woman's shoulder and device hanging from the side of the wall that's holding the Punch puppet with dildo.  

The torso of the Lemur transforms into the bodies of the humanoid being seated on the wall.

c) Left lower leg becomes inward slanting cut into the wall while Lower right leg bones become a dildo, the right hand and wrist joint become the Punch and Judy puppet's cap.

d)  Head of lemur becomes integrated with a human face. 

The eye sockets become bars on the side of the face. 

The ears become slightly humanised as do the fans. 

The central ridge is retained as an indentation
