Captain Planet and the Planeteers - Season 3 Episode 10
Hog Tide

In this story, we supposedly learn of Captain Planets REAL first adventure... Gaia recounts how Hoggish Greedlys "Godfather" grandpa, Don Porkaloin, built Decco developments too close to the oceans threatning the sea-life. What shocks the Planeteers is that Gaia reveals she brought forth eco-warriors - 1940s counterparts of the present day Planeteers - to stop Don Porkalion. These Planeteers could also summon Captain Planet, who went about de-constructing Porkaloins deccos. The Planeteers are left confused about whether or not Gaias story was real, totally missing the point about building too close to the water.
