Free Waterfall, Sr.

Free Waterfall, Sr. was the father of Free Waterfall, Jr. and the son of Old Man Waterfall. He was the head of Penguins Unlimited. He fought 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 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 organization's humanitarian efforts. Waterfall Sr. was pecked to death by penguins when Bender led them to war. His father vowed to avenge his death.
