Free Waterfall, Sr.

Free Waterfall, Sr. was the father of Free Waterfall, Jr., the son of Old Man Waterfall, and was the founder of the ecological group Penguins Unlimited.

He led a non-violent protest against having a dark matter tanker fly past Pluto, which had been turned into a penguin reserve. He led a peace ring around the tanker, which failed due to the three-dimensional nature of space. When the tanker's captain dumped the entire load of dark matter onto the penguin reserve, Waterfall, Sr. observed that the dark matter was nature's "love drug" and that it 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 Leela, whom thought she had found some sanity in his organization's humanitarian efforts. However, Waterfall, Sr. was pecked to death by penguins when Bender led them to war, and his father vowed to avenge his death.

Waterfall, Sr. fully embraced his life as a conservationist. He stopped his followers from clapping their hands because it could kill spores that would eventually form a nutritious fungus. He also told his followers that to keep their hands warm by sticking them between their buttocks, declaring it "nature's pocket". As he was being killed by the penguins, he said to make sure that they used every part of his body.
