Minstyngar were animals that lived in packs on Kashyyyk. A massive simian creature, the minstyngar haunted the lower levels of the Rryatt Trail. The minstyngar had a rudimentary social structure. Although many adult minstyngar could be found roaming the Rryatt Trail, the elders and younglings were often hidden deep in the forest, far from prying eyes. Their skin was either a shade of green or brown.
Minstyngar appeared in the video game Star Wars Galaxies, a massively multiplayer online role-playing game developed by Sony and published by LucasArts, prior to its closure on December 15, 2011.
