The Three Billy Goats Gruff reminded me of these illustrations I did for Frances Watts’ book The Middle Sheep. It was one of the books I most enjoyed illustrating. I’m not a middle animal, but I’m one of three siblings. Possibly not as cute as I should have been. Ha ha!
Here are some of the sibling animals who featured in the book.

Sibling snails: sensible big sibling snail, cute little sibling snail and poor, overlooked middle snail.
The Middle Sheep is suitable for the six to nine-year-old age group (give or take a birthday) and can be purchased online here or here or ordered in by your favourite local bookseller.
