Plastic Forms around Anamatronics ?

Christopher

How come some Anamatronics have areas with plastic around the mechanical part. Is this in the case of the appearance of muscles or tissue sliding on the animatronic character ? If not what is it's purpose and is there a tutorial on when to place such plastic around the mechanical part of the character ?

Can you add a picture of one? I think you are talking about tubing but am not sure.

If so, tubing creates a no slide area that has some grip and dampens noise where two metal sections might touch with a clink.

Sorta like these two images. On the first top image there is some plastic in areas. The bottom image is more for a head costume,  but I included it anyhow.
