Bionicle sets with staffs identification I bought this series of 4 lovely small monsters/gods at a garage sale.

Body, arms, legs and hands are made of Technic and are studless.

Help me to identify:


if they are part of an official set of The LEGO Group, and which one?
which are parts such as the masks, the foots (which are also used as
the support of the masks), the weapons?




Update: This might be from the Bionicle / Turaga (BrickLink) or similar range. So any links to introduction to this series would be welcome.
These are indeed Bionicles

Green: 1418: Matau

Blue: 8543-1: Nokama 

Red: 8540: Vakama 

I think the last one is 8542: Onewa, with the mask of 8545-1: Whenua
