Random House Children's Books sent me a copy of these for review (thank you). They are now available at your local bookstore for purchase.
The Cookie is based on the two characters tricking each other. It involves an invisible doughnut and a real cookie. Nugget keeps tricking Bean Dog; Bean Dog gets even.
The Ball begins with Bean Dog and his shiny new ball. When Nugget wants to play, he says no, but relents. Unfortunately, the ball bounces in the bush. They have to become Ninja's to recover it.
If you have a reluctant reader, this would be a real good series to start them with. The story is a bit silly and the characters are, too. Once a child finds out how easy it is to read, they are usually ready to move on to another fun book. Reading is a necessary skill in life; teach them early.
