7 Do you have an idea for your next book?
The next book is about a moth who yearns to fly to the moon. It coincides with the 50th anniversary of the Apollo moon landing. When I was a boy I was obsessed with space flight and the NASA shuttle programme, so it's been a joy to do some space related research on this book.
8 Do you books always have animals in?
Aside from a big, bearded lumberjack, animals have featured strongly in all my books. But whenever animals feature they are simply a way of telling human stories in a slightly fluffier, cuter way.
9 How do you decide the names of your characters?
'Big' Jim Hickory came about as hickory is a wood that is mostly used to make axe handles, so I thought that would be an apt name for a lumberjack. I decided not to give the bear from my first book a name at all, simply because I didn't think it was necessary.
10 What books did you like to read when you were younger?
I had a very healthy Mr Men collection when I was a young boy. Aside from that I was always more interested in comics - I loved The Beano in particular. I think it was my love of comics that really drove me to want to be an illustrator when I was older.
11 Do you sometimes feel like Percy?
Thankfully, I don't think I've ever been as desperate for food as Percy. It is always pleasant if you've ever been on the receiving end of a stranger's generosity though. I think that's something we can all empathise with.
