All that glitters is not gold . "A long way out in the deep blue sea there lived a fish. Not just an ordinary fish, but the most beautiful fish in the entire ocean." This is a book I have some trouble with. It is beautifully illustrated, and the glittery silver scales make it very appealing to children. However, I am not entirely sure it is sending the right message. I like to give the author the benefit of the doubt that he meant well, that the overall message is that vanity and posessions will not make you happy. But ultimately the solution to the Rainbow fish's problems give unclear messages, and can possibly be interpretated that to make friends you need to buy them. Other interpretations have been covered comprehensively in other reviews and include possible biass towards communist values and a want for sameness
Output:
NEG
