All the cartoons in the book are brilliant, and hilarious. Most of the time they are similar to the words, but sometimes they are variations of what is being said, and they always add another layer of comical humour on top. I've always loved how Jeff Kinney draws Greg, a stick figure, it makes him look truly wimpy indeed, especially since all the rest of the characters are chunky and thick.
Diary of a Wimpy Kid: The Third Wheel is a great addition to the Wimpy Kid family. Its full of laughter and jokes that both children and adults alike will enjoy. It is a perfect read, gift and present. Maybe consider giving it as a christmas present?
-And when Greg stuffs things up, its always Rowley who gets the win in the end, brilliant.
