Ratty, an ENORMOUS woolly, vegetarian rat, lives deep inside the crater of an ancient volcano nestled in the rainforest. One day, he spies a particularly delicious-looking fruit high in the treetops, and sets out to reach it. From this high vantage point a spectacular view stretches before him – the world outside his mountain crater. In this big outside world, Ratty imagines, the fruit must be much sweeter, the bird songs more beautiful and the other animals far more interesting and sophisticated, and so he sets off in search of better things. But when is he is asked to attend a dinner party by a crocodile who seems just a bit too friendly, Ratty realises that perhaps there is no place like home after all.
