Prunella's 4th grade class is a class that is taught by an unnamed teacher that has yet to be seen or mentioned. The class has been seen only a few times in the series, mostly when it's an episode that centers around Prunella Deegan. It's safe to assume that the other 4th Graders seen around Lakewood, including the members of the Tough Customers (except for Binky) are most likely in this or some other fourth grade class. Prunella sits towards the rear of the classroom, but not all the way to the back.
