simonsays - you need to find anagrams of Tabitha and Madison. That provides the definition. (The anagram of Madison is a less conventional spelling of a familiar word.) There is a clash in the third cell from the outside.
I knew about the anagraming, but failed to realize that Madison was also one. Thank you very much. Only B and D to understand now and will be finished.
What a fantastic puzzle!
Jim - the character is Pink-i.e. So I think the colour is important. It doesn't worry me as I don't send in an answer.
I'm stuck on clue D if anyone can help. Thanks.
Thanks everyone - finally finished. I hope we get more like this in future. By the way, I assume that the 4 spare letters in the ring with the 16 clashes don't have any special significance?
