I am at the stage where I am looking for the 30 cells to highlight. Having read all the previous posts, I gather that I should be looking for two 9 letter items, read in reverse, with two 6 letter items above them. I am not sure whether the items are animal or mineral, but apparently they have 12 legs between them, which suggests that 3 of them are animal and the other is mineral. I have stared and stared at the grid without success. Am I on the right track, or barking up the wrong tree?
