Mr Pinkwater,
The young son of a friend of mine is at the age when all things gross are of interest and she happened to mention that his current interest is ear wax. I seem to remember that one of your books dealt with a creature that ate ear wax but I can't tell from the list of titles of your books which book it is – can you help me and make a little boy happy?
My nephew as a child was a fan of your books and even sent one to you which you kindly autographed. I hope this request is simpler.
Many thanks. – Faith
It's The Moosepire.
