This is book is about, author imagine him and zombies coming out of the camp toilet. Grandpa in undies and a robe, baby brother Manny running around pants-less, Greg showing his rear end getting out of a pool. One image shows a teen smoking outside an ice-cream place. Greg is full of wrong-headed decisions, as usual -- it's a big part of the humor. That’s why parents will appreciate Greg's always-well-meaning mom who, this time, tries to get the whole town to go screen-free for a weekend and clean up the local park. Overall, I really recommend this work, the words that author uses is not hard, it's really easy to understanding for kids.
