Biography
Filburt, a neourotic, somewhat nerdy anthromorphic turtle, had been a friend of Rocko and Heffer's since high school. 

When Heffer fell into the clutches of a mysterious sausage worshipping cult, Filburt came up with an elaborate decepetion to try and trick the cultists into releasing Heffer. In the ensuing commotion Emmett Brown would slip from the back of the jury rigged giant sausage contraption to save Marty McFly from the clutches of the cult and Biff Tannen. Unfortunately the deception was compromised and Rocko, Filburt, and Heffer were attacked by the cult members. He, Rocko, and Heffer were saved, however, thanks to the Delta Flyer and its transporter technology. (Star Trek: Voyager - Dark Realm)
