Race of aliens from Doofundland who are exceptionally smart but socially awkward. They are brilliant engineers, have mastered space travel and many of science mysteries, yet cannot verbally talk to each other. They all dress similar to each other but bits and pieces of flare is allowed. They love capitalism and anything can be available to anyone.
