Battle of the Dum Diddys

Rate this book
Hey! Where Is Everyone?





That's what Bernie Bridges wants to know when he can't find any of his friends. Everyone has disappeared! And when he finally does find them, they're acting really weird. For instance, his shy friend Chipmunk thinks he is a fearless warrior, and football star Jennifer Ecch thinks she is a princess. What is going on?





Soon Bernie realizes that everyone at Rotten School is acting! They are all playing parts in a big battle. A battle between the Dum Diddys and the Knighty Knight Knights. But it's not a real fight. It's a video game called Wungo Warriors—and everyone has to pay that spoiled rich kid Sherman Oaks to play.





Bernie can't let Sherman get away with this. He has a plan to outsmart Sherman—by bringing the Wungo Warriors to life!





What Bernie doesn't know, though, is that a real-life battle between the Dum Diddys and the Knighty Knight Knights could shut down Rotten School forever.

The battle between playing for real versus video games. Which will win?

I actually started on Book 12 of the Rotten School series. It was really good. Those kids are something else. They remind me of my friend's crazy nephews always drumming up something fun and crazy.

This has been an enjoyable series so far. It's not your Goosebumps or Fear Street, but perfectly kids being bad.

THE DUM DIDDYS, are in fact dum. the ludicrous shenanigans that they do in this epic adventure are enough to leave anyone fiending for more. the awesome adventure of the diddys are so well written, and the sean combs cameo was unexpected, even with the title of the book. the ohio setting was truly ridiculous, but fun! dum diddys are some of the best cast of any book ever. i love these books and the five star is obvious. go diddys go!

I actually really loved this one. Bernie took a bunch of couch potatoes playing video games and turned the activity into active outdoor sport. For once, Bernie did something good.

Probably a reason why this was chosen by my 4th grader, but it's still fun to read with her :o)
