Peet, Bill "The Whingdingdilly" - 1982
My kids were avid readers, they loved any children's book from the first board books until they started reading adult books. And there are quite a few that were so wonderful that I loved them just as much as they did.
One of them is "The Whingdingdilly". Scamp is a farm dog who is bored with who he is. Every other animal seems to have a better and more exciting live than he does. He asks a witch to change him into another animal. He only doesn't tell her which one ...
The books is full of wonderful illustrations. It's a lovely story to read to little children and to be read by older ones alike. It teaches us to be content with who we are because the grass might look greener on the other side but it might not always be the fact. Wonderful message along with a fantasy-like adventure.
From the back cover:
"Scamp learns to be content with his dog's life when Zildy the kooky witch turns him into a whing-dingdilly. "
When researching when this book was written, I learnt that the author was not just an illustrator who wrote children's books but also a Disney writer who worked on quite a few big Disney films.
