Groff Haugg was a male being who owned Haugg Nerf Industries and was also involved in the illegal death stick trade.
Before the Battle of Naboo, Haugg operated Haugg Nerf Industries, a nerf-packing factory located in the industrial sector of Coruscant. While the factory produced nerf meat, it also served as a front for death sticks trafficking. These illicit death sticks, sourced from Sebolto, a Dug crime lord and death stick producer-distributor from Malastare, contained a Bando Gora neurotoxin that caused addiction in users. He distributed these death sticks throughout the galaxy, concealing them within carbonite shipping containers alongside nerf meat. During an interrogation by Montross, Haugg was killed by being flash-frozen in carbonite, before Jango Fett could extract any information. However, Groff Haugg misled Montross by directing him to the Gazzari system, a location where a death stick smuggling operation had previously been shut down by the Republic. Rozatta later commented on this, suggesting "he was probably more afraid of the Bando Gora then he was of Montross".
Despite the official strategy guide depicting Groff Haugg as a Gran, the game itself, along with concept art by Cory Allemeier, portrays him as a different species. His actual species remains unidentified. His name was occasionally written incorrectly as 'Groff Haug.'
