Jumble Wood by Helena Covell
Far, far away there was a wood. A jumble of twists and turns, ups and downs, and unknowns. The little creatures that lived there each had a thing that made them happy... all of them except Pod, who just can't seem to find hers. Exasperated and sad, Pod sets off to discover where her 'happiness' might be hiding, only to find it in the friends she meets along the way.
