Whizzer, a Twi'lek well past his prime, had connections to the criminal organization run by Jabba the Hutt on Tatooine, specifically his cartel.
By the year 3 ABY, Whizzer was indebted to Jabba, owing him both credits and spice.
On one occasion, Whizzer was ambushed by Big Gizz, Spiker, and other individuals belonging to Jabba's swoop gang. Spiker feigned Whizzer's execution as a scare tactic, stopping just before the fatal blow. Whizzer subsequently paid off his way out of the situation by letting Big Gizz try some of his Ryll.
