Squornshellous Zeta Dimly illuminated and very very swamp-intensive, Squornshellous Zeta is the source of almost all the Galaxy's mattresses. Said mattresses (all of which are called Zem) spend most of their time flolloping, globbering, volluing, and vooning. Said activities make the planet a favourite destination of etymologists. The Zem themselves remain a foot tall, until they are freeze-dryed and cleaned, and made into mattress-size corpses (which are promptly used as mattresses). It is a process which, strangely enough, they don't seem to mind at all.
