In Tweak Tweak, a mama elephant and her baby go on a long walk, during which she encourages him to tug her tail twice whenever he has something to ask her — hence, *tweak tweak* — whereupon they would stop so she could patiently answer all of his questions.
Kids love to ask their parents questions about all sorts of curious things at any place and any time — but especially when they are out and about. Hence, both kids and their parents would be able to relate to the familiar parent-child dynamics in this sweet tale (tail?).
The questions asked by the baby elephant are also conceivably the kind of questions that a typical child would ask or wonder about: “What is that [animal]?”, “What is it doing?” and “Can I _______ [too]?” Ditto the pragmatic yet encouraging answers given by the mama elephant, which any parent would do well to take a leaf from.
So as not to give away too much of the story, it suffices to say that thanks to the clever way in which the story is structured and written, the overall message of the book — that everyone is different and has his or her own strengths — comes through very well. I also loved how the mama elephant trusted the baby elephant to lead the way back home.
