In order to prevent being deported to the National Park, Square Bear feigns a broken bone while his companions carry through with the act of convincingly accusing Peevly of criminal neglect.
The Hair Bears have their paws full when they are ordered by Peevly to baby-sit Percy Panda, a mischievous little bear who was on his way to the St. Louis Zoo before being misplaced.
In a ploy to keep from being shipped to the National Forest, the bears persuade Peevly into starring an a re-enactment of the story of Noah's Ark. The bears use the ark to break zoo with the other animals.
The bears seek greener grass by busting out of the zoo and heading for the National Forest. There they fall a foul of two bank robbers using a shack as a hideout.
The bears are forced to share their cave with Arnie, a lovesick gorilla who pines for female gorilla Gloria. The cologne Bubi invents to make Arnie irresistible has odd side effects.
The Hair Bear's dream of travel to outside world skyrockets when they answer an ad from Professor Neilsen Rockabuilt, offering a job for three persons seeking good pay, adventure and fame.
The animals send Peevly's name into a loving hearts club in hopes he gets hitched and leaves the zoo. But the bride-to-be turns out to be a plus-size battleaxe that takes full control of the zoo.
