Free Waterfall, Sr.

Free Waterfall Sr. was the father of Free Waterfall Jr., and the head of Penguins Unlimited. He thought against having a tanker filled with dark matter flown past Pluto, which had been turned into a penguin reserve.

When the tanker's captain dumped the entire load of dark matter onto the penguin reserve, it appeared that the dark matter was nature's "love drug" according to Free Waterfall Sr., whom had discovered that dark matter made the penguins extra fertile.

To avoid overpopulation of the penguins, he initiated penguin hunting season as an effort to lower the population, much to the dismay of Turanga Leela, whom thought she had found some sanity in his organisation's humanitarian efforts. Free Waterfall Sr. met his end when he was pecked to death by penguins when Bender led them to war.
