Because Yogi can't stand the thought of being cooped up in a zoo for the rest of his life, he hatches an elaborate escape plan.
Salvaging car parts from a failed fishing expedition, he constructs a getaway "Supercar," complete with a picnic basket rumble seat for the three orphaned cubs.
It turns out to be the secret clubhouse of the Bike Brigade, three boys who ride bicycles and operate a shortwave radio.
Using their radio, the boys call ahead to their cohorts in other clubs around the country to watch for Yogi and help him in his getaway.
Wally Gator, another zoo fugitive, inhabits a spooky steamboat, complete with ghostly illusions intended to scare away zookeepers.
While the anonymous ghost pursues the hunters, Yogi and his friends are rescued by another club, the Swamp Foxes.
When Ranger Smith sees through the disguises, the bears escape to a hot air balloon and take off.
