I don't have to worry about the elegance anymore, the haddoni ate it that night, along with a sea urchin and was half way through pulling in the rock on the bottom right covered in zoos!
I pulled the rock out and could sea a bit of sea urchin (blue tux) but could do nothing about it. Next morning he had spat out the urchin and the elegance.
I think I am going off the anemone!
Sorry about that.
But, hopefully you will just sell it, as opposed to killing it -- it did what Haddonis do.
