This great kids book teaches kids, in a fun way, to always try to have a positive attitude. The Negatees is a sad and pessimistic creature who lives in the land of the smelly treeshe continuously enjoys the misery of knowing that nothing good will ever happen to him. In the end, lets hope that the Negatees learned his lesson and will act more positively as he sees good things happen to a purple creature because he was positive and happy. The wonderful collaboration between author Adam Wallace and illustrator Heath McKenzie has given kids some pretty cool and amazing books.
