Book 6- Boar's Treehouse -Paperback

Mom shooed Boar, Junior, and Hardy out of the house and told them to play outside. As the kids wandered around the backyard, they spotted a big oak tree.  The kids thought it would be cool to build a treehouse on it.  But how?  Boar remembered a story that Dad had told them once, about how he and his friends had built their own phone system using tin cans and string. Maybe they could do the same and use it to communicate while building the treehouse. They tested their phones by talking into them and listening to each other. It worked!  You will laugh out loud as you watch the kids figure out how to build their treehouse, which is much taller than they are.
