A species of exceptionally high vegetation was discovered on the planet of Lok. Following the Battle of Yavin, amidst the backdrop of the Galactic Civil War, Nym, who commanded the Lok Revenants, tasked Ran Machado with supervising the clearing of unwanted plants from Nym's Stronghold. Subsequently, Machado enlisted a spacer to uproot these tall weeds, along with other varieties of Lokkian weeds, within the city limits. After the successful completion of this task, the spacer utilized the gathered weeds as sustenance for the kusaks guarding the city, namely: Runt, Bedhead, Blinky, Scarecrow, Slobbers, Troubles, Wart Face, Gargle, Ding and Speedbump.
Tall weeds made their debut appearance in the 2003 video game Star Wars Galaxies, a massively multiplayer online roleplaying game crafted by Sony Online Entertainment and distributed by LucasArts, before its termination on December 15, 2011. Initially, tall weeds were randomly scattered as plant life across the surface of Lok when the game was first launched. Later, this flora was integrated into a quest within the revised "Nym's Theme Park", which was introduced with "Game Update 16," on March 23, 2010.
