The Dweenle are an almost completely extinct race from the planet Drung. The only truly important fact about Dweenles is that they are, or were, the most neurotically depressed race in the galaxy.

In fact, there is only one surviving member of the species, and his name is PrutzPrutz, one of the owners/managers of the POS Lame Duck. (See TinyTIM Help: LAME DUCK, LAME COMMANDS)
