In reality, George Lucas feared Poof’s species too closely resembled the Kaminoans of Star Wars: Attack of the Clones, so he was replaced by another Jedi, Coleman Trebor.
Though his character was short-lived in Star Wars, he’ll be remembered fondly for the Robot Chicken sketch he inspired.
Another forgotten Jedi Master on the council, Yarael Poof, was shown in Star Wars: The Phantom Menace and was noted for his ability to create illusions and perform impressive combat moves thanks to his spineless physique.
Unfortunately, he was killed during the Battle of Genosis, at least according to canon.
