- "The mattress globbered."
- —The main mattress pastime[src]
No one really knows what mattresses are meant to gain from life. They live quiet, private lives where they "flollop and vollue" to amuse themselves.
Mattresses make a variety of noises that are not supposed to be able to be made by other lifeforms throughout the galaxy, such as willomies, globbers, flurs, and glurries. Those being only a few examples. Mattresses are also capable of doing things floopily, meaning in a floopy manner.
The book Sqornshellous Swamptalk is a dictionary of mattress vocabulary.
