Like Inkpen's Kipper the Dog for slightly older readers, Wibbly Pig has been published internationally and has sold millions of copies worldwide.
Some of the Wibbly Pig books also have activity features such as flaps which can be lifted to reveal additional art.
Wibbly Pig is a favourite of pre-school children and an ideal introduction to simple ideas through intelligent yet basic text and questions.
Like Kipper, Wibbly Pig also exists in the form of a life-sized costumed character who can greet and interact with children at special events such as library story hours.
The series premiered on PBS Kids Sprout with the new season of The Good Night Show, on August 27, 2012 in the United States, and it featured the characters redubbed with Canadian voice actors.
