Tach

The Tach from Kashyyyk was an animal that lived and died in the Shadowlands of said Planet. It was hunted ferociously by Czerka employees who wanted to make Tach Juice out of them, but even more by Madclaws with a Monkey Fetish. Darth Revan once went to Kashyyyk in an effort to wipe out the entire Tach population in his quest to get paid and he nearly succeeded. Jolee Bindo lived with the Tach for twenty of our standard years, I dont even want to speculate about his reasons.

Behind the scenes
One specific Tach made it off planet and traveled to Hollywood to become a moviestar with succes, he starred in the Pirates of the Caribbean trilogy as: Jack the undead Tach.
