Hi Jolan.
I'm sure Croeso will be happy with the answer and he never specified clues.
It's just that I'm not so kind as you and was hoping to make them work just a bit towards the answer.
For the other clue about a drip etc. I have an idea for the answer but I can't quite make it out. A clue would be
"Cave decorations". It's a really easy clue as I'm not confident that the answer is correct.
