2MrFreeDragonThis is white monster or green or broken?

These are 5 green separate pieces.
4) The monster is located within orange square (so, only 12*12=144 unknown bits to find)
But this is not 12 to 12. And less.

Yes, not 144 if you took into consideration the 5th clue:

I decreased the search space from 256bit down to 144bit (orange space). The unknown space even less as the monster does not touch (horizontally, vertically or diagonally) the green border.
