The Gampassa, a species of turtle, had wrinkled, gray skin and a rounded, oblong body that included a brown shield shell. The creatures had six triangular flippers that ended in points; those limbs were situated symmetrically on both the left and right sides, and their forelegs grew much longer than the others. A short tail adorned the species' anterior, and nostrils were located between the eyes on the creatures' bulbous heads. At least one specimen was 2,310 meters long.
The Gampassa species was native to the oceans of the Mid Rim planet Glee Anselm. Due to the creatures' enormous size, the Nautolans, another native species of Glee Anselm, used the species' shells as locations for their villages, complete with landing platforms built atop the shells. Every couple of centuries, the turtles would alternate with going above or below the ocean level, and entire generations of the species' native Nautolans would either be born above or below water accordingly.

The Gampassa species was intended to appear in Star Wars: The Clone Wars' second season episode "Children of the Force," released October 9, 2009, although it was cut from the final episode. Concept art for the species was included in the extra features of the 2010 Star Wars: The Clone Wars The Complete Season Two Blu-ray release. One of the images was signed by concept artist Jackson Sze, dated to December 12, 2007.
The species was further discussed in 2012's Star Wars: The Clone Wars The Complete Season Four. In that, Supervising Director Dave Filoni discussed more details surrounding the turtles' intended inclusion in the series, including showing concept art and Maya 3D models for landing platforms aboard the creatures' backs. Lead character designer Kilian Plunkett also asked Filoni what the turtles were eating, given their size, and Filoni imagined it would be difficult for them to find food sources in their environment. The 2013 Star Wars Blog article "Drawing from the Imagination: Mythological Creatures in Star Wars, Part 2," written by Tim Veekhoven and Kevin Beentjes, included the Gampassa and noted its resemblance to the Hah-nu-nah turtle island of Native American oral legend. The plural form of the species' name was never established.
