The Kingdom inspector is making his rounds and Vernon, Populah and Loopy are cleaning up Under in preparation, kicking everyone out. If the kingdom’s dirty, then Russel will lose his crown, so Bob sets out to turn the town into a dump. Unknowingly Auntie First uses an obscure legal loophole to swap ownerships of hers and Russel’s kingdoms, leaving Vernon and Loopy to clean up filthy Near Under in a few mere hours. Meanwhile, Russel, Gus and Populah have to get the last stamp required in Under’s Stamp Collection from Elpsun C's post office (without which he will lose his crown also).
