The Grunka Lunkas are small orange men who inhabit the planet Wormulon.
They are employed by the Slurm Worms to work in the fake Slurm Factory. They spontaneously burst into song with a warning about asking questions of Glurmo. They aren't paid to sing and Glurmo denies them their bathroom break for singing when they should be working.
- They greatly resemble Oompa Loompas. More specifically, their appearance in the film "Willy Wonka and the Chocolate Factory".
- It's possible there are female Grunka Lunkas, but they're unseen. As there are male and female Oompa Loompas.
