Grunka Lunkas are a race of orange-skinned, green-haired humanoid midgets from planet Wormulon. They are either unwilling or unable to speak normally and thus communicate only in song, usually making up rhymes with lines of nonsense including the name of their race. Per example: "Grunka Lunka dunkety dife, I'm really bored and I hate my life."
Although it is widely believed that Grunka Lunkas have been exploited as cheap labor to produce the popular soft drink Slurm, they are in fact merely part of the fake factory for the benefit of tourists. They are threatened with severe consequences if they divulge how it is really produced. Since this encyclopedia has already divulged that, we hope there will be no repercussions for them.
