Can we try to figure out what the riddles are?

So far for the 1 Echo riddle the correct answer was &quotA cat’s shadow.&quot

I think the wrong answer was &quotA whale’s eye.&quot

What question could have suggested those?

Something about secrets perhaps? Cats are known to be full of secrets down here in the Neath.

My money is on &quotWhat’s underneath a cat on a sunny day?&quot
On most occasions the wrong answer would be whale’s eye.
