Yogi Bear & his Holiday Jolliday Tours, takes himself, Boo Boo, Quick Draw McGraw, Augie Dogie & his dad Doggie, Snagglepuss, & Huckleberry Hound to Long Beach, CA to see the Spruce Goose - the largest plane ever built, of wood, by Howard Hughes. Yogi's always getting lost & takes them to an, "Off Limits," part of the plane & it closes & they can't get out. Yogi presses all the buttons on the control panel. The plane starts up & leaves the hanger & Yogi thinks it's all part if the show, until he has to fly it - it's a magical plane. Meanwhile, two aliens, Firkin & Merkin come to invade Earth & are scared when they see the Spruce Goose & leave to another part of our planet. Animals in the South Pole are trapped & can't get to food so Yogi takes the gang & the Goose there to help. They discover Bernice - she was trapped in the cargo area - she's a mean tomboy. They save the animals. Then, an ocean liner's adrift with animals aboard and their poachers abandoned them. They go to save them too just as the aliens also come & once more are scared away by the Goose. Quick Draw changes into his alter hero; El Cabong - to help. Yogi takes the animals to an island but someone's on it... Dread Baron & his sidekick Mumbly. They've been marooned there since Dread crashed his plane. They want off the island but Yogi & gang don't trust him. He promises to reform - hah! They take him onto the Goose but Dread traps them to go to the island of Moolah Moolah. On Moolah there's a statue that resembles Dread & the natives now worship him. He has them load lots & lots of gold onto the Goose. A volcano erupts & they must leave. Once up in the air they must throw the gold out because the plane's too heavy - Dread & Mumbley follow the gold - & now the natives worship Mumbley. Yogi somehow ends up back in Long Beach (remember the Goose is magical). Bernice is reunited with her mother & Yogi takes the gang back to Jellystone Park. Cute movie for kids of any age.
