Concerned about the terrible state of the environment, the entire animal kingdom from Hanna-Barbera gather for a meeting in Jellystone Park, chaired by Yogi Bear. They decide to leave their homes and search for "the perfect place" — a legendary and trouble-free place free of pollution, deforestation, and other forms of mankind's despoilment and has a few simple problems. Jellystone maintenance man Noah Smitty helps them build a flying ship (which looks like Noah's Ark with a propeller on top) for their journey, and they decide to name it after him. Because "Smitty's Houseboat" is too long to paint on the bow, they name it "Noah's Ark." With Yogi at the helm, they travel to places around the world, searching for "the perfect place."

They start by driving down the highway into the ocean, where they soon end up on the back of a sleeping Moby Dick. Huckleberry Hound is sent down to wake him. They then end up stranded in the Sahara Desert which they originally mistake for a beach. The desert sun causes Yogi to hallucinate and believe he is pharaoh King Tut and his friends are his slaves, until Boo-Boo and Noah Smitty arrive. Some moments later, So-So the monkey spots an oasis, which is "the perfect place." As Yogi and crew settle down to make themselves at home, Lambsy spots a "dragon" which turns out to be a construction vehicle developing a new city. Yogi and the crew then take their leave of the area. They arrive in Antarctic territory, which is a brand new "perfect place." They begin settling there, until a similar situation happens like at the oasis. Next, Yogi and the crew wind up in outer space upon going up too far, which is a new and improved "perfect place." It isn’t long before Earth ejects its "junk" (missiles, satellites, etc.) into space.

With the Ark back on earth and sailing the sea, the animals give up hope on finding "the perfect place" and tensions arise between them: Huck throws water down a pipe which causes Dum Dum to emerge and throw water at him, Quick Draw McGraw insults Snagglepuss’ slicing of salami, Peter Potamus insults Magilla Gorilla by telling him he looks like a gorilla, and Lippy the Lion grows tired of Hardy Har Har's complaining. Yogi Bear becomes aware of this just as So-So spots a typhoon coming. The animals struggle to survive the typhoon. The typhoon lands them on top of a mountain, and the animals almost believe that they’ve found what they’ve been looking for... only to be disappointed again when Yakky Doodle returns with an empty tin can and the animals notice a deforestation occurring.

At this point, the younger animals (consisting of Atom Ant, Augie Doggie, Baba Looey, Benny the Ball, Boo-Boo, Ding-a-Ling Wolf, Lambsy, Pixie and Dixie, Shag Rugg, Touché Turtle and Yakky Doodle) decide that they should all simply go back home and clean up the messes that they were trying to escape. This decision is met with unanimous approval, and the animals all head for home so that they can start turning it into "the perfect place". During the credits, Wally Gator and Squiddly Diddly are cleaning the rivers, Paw and Shag Rugg are picking up garbage around their house, and Yogi Bear picks up a recently discarded hamburger wrapper.

• Although this was the pilot for Yogi's Gang, some changes were made for the series:
  • Noah Smitty was written out, and only the animals were on the ark.
  • The vessel’s name was changed from "Noah's Ark" to "Yogi's Ark".
  • Some of the animals, such as Top Cat, were also written out, thus giving the ark a smaller crew.
• This one-hour feature was later turned into two half-hour episodes of Yogi's Gang with new intro and concluding sequences for each episode. To fit the feature into these new time frames, some of its sequences were shortened or edited out.
• The song "The Perfect Place" is sung six times throughout the film, and would later be remade as the theme song for Yogi's Gang, with different lyrics.
