In 32 BBY, Queen Amidala of Naboo called for a Vote of No Confidence in Supreme Chancellor Finis Valorum, Grebleips and his delegation were present, joining the fracas that ensued throughout the Grand Convocation Chamber. Shortly before the Clone Wars, Grebleips funded an extra-galactic survey. As the war neared its end, he became part of a Delegation of 2000 legislators who filed a formal protest against Valorum's successor, Palpatine, for actions they perceived as unconstitutional. When Palpatine turned the Republic into the Galactic Empire, Grebleips was arrested by Imperial Intelligence on charges of conspiracy and treason, for plotting with the Jedi Order to remove Palpatine from office.
- "Grebleips" is "Spielberg" spelled backwards, a direct reference to director Steven Spielberg.
- Grebleips, along with his fellow Brodo Asgorians, were seen in Star Wars Episode I: The Phantom Menace as an Easter Egg placed in the movie by George Lucas after his friend, Steven Spielberg, put references to Star Wars in his film, E.T.
