Fluid sac

"I only care about us being together&mdash;forever.''" "You&mdash;you really mean that?" "''From the bottom of my fluid sac."

- Sy Snootles and Ziro the Hutt

The fluid sac was a part of the Pa'lowick anatomy.

Behind the scenes
The fluid sac was first mentioned in "Hunt for Ziro", the ninth epsiode of the canon animated series Star Wars: The Clone Wars third season. Although the subtitles for "Hunt for Ziro" spelled sac as sack, the letter k was removed from fluid sac's spelling in later sources published on StarWars.com. This article assumes that sac is the correct spelling.
