Children's books we never had
The Little Mole Who Knew it Was None of His Business is, quite simply, one of the funniest books you are ever likely to read (as long as you are not easily offended, that is!), with its unusual take on a natural bodily function combined with a simple tale of nature and discovery. When the little mole of the title discovers a pile of, well, pooh, on his head, he is absolutely certain that it doesn't belong to him, but sets out on a mission to discover who exactly the culprit really is. His investigation takes him into the world of many animals, as he wanders and compares the pile on his head to the piles that animals leave behind them. Outrageously funny, this cracking little book is an absolute delight and not only gives children the chance to talk about one of their favourite topics for discussion, but is also an intriguing way of introducing the idea of a nature trail, taking them on a trip that will leave them both laughing and learning.
Why I've copied and pasted the whole review from Amazon.com? So you know what this book is about and mainly because I do have a Russian Translation of this fine book in our galleries, for viewing pleasure of my Commrades. It does look rediculously funny when it's in your own language
