The fictional national park called "Kookamunga" (short for Cucamonga Valley, although it is known as the Kook) is overseen by a white pig named Iggy Arbuckle, who created the fictitious Pig Rangers. His sidekick is Jiggers, an industrious beaver, while his arch-nemesis is Stu, a catfish that constantly tries to exploit the park for wealth. Most of the episodes follow Iggy and Jiggers' adventures in preserving Kookamunga's ecosystem from Stu's schemes.
Iggy and Jiggers must stop Mount Kaboom from erupting.
