Emporer Pickletine Rides the Bus is an Origami Yoda book. The book is the last in the series.
After winning the fight for their field trip to Washington D.C., the Origami Rebel Alliance is ready to go. There's just one catch: Principal Rabbski has banned origami. Dwight folds a Yoda out of a lime fruit roll-up, and has to stop Harvey's Emporer Pickletine from turning the trip to the sour side.
Instructions are included in the back of the book. They tell how to make Emporer Pickletine and Flying Vader.
