ourists have departed Brownstone National Park where Humphrey lives, leaving trash everywhere, despite signs asking tourists not to litter the park. The park ranger initially starts to pick it up himself, but then decides that he should not have to do it because he is the boss. He then calls Humphrey and the other resident bears and asks them to "put it in the bag", while singing and dancing to a catchy song. The bears happily collect the trash, bouncing and jouncing until they discover the ranger's actual motivation. With Humphrey dropping the ranger into a garbage can, the bears angrily dump their bags of refuse on the ground. Realizing that he should at least reward the bears for their assistance, the ranger prepares some chicken cacciatore, but says that he will only give it to the bears on the condition that they clean up their sections of the park. All of the bears then move their garbage into one section, leaving Humphrey to clean it all up himself. He does this quickly by stuffing the garbage into a bag, but as he is returning to receive his dinner, the bag gets caught on the twig of a tree stump and rips apart, letting the garbage out. The ranger then gives him a new bag and Humphrey follows the garbage down the line all the way to a cliff, but falls off as he puts the last scrap in the bag. Next, he attempts to conceal the garbage under a bush, but the bush turns out to be the home of a rabbit, who disgustedly pushes it back out. Humphrey then tries to burn the garbage with a match, but is stopped by Smokey Bear, who reminds him that "only you can prevent forest fires." Finally, Humphrey puts all of the trash into a hollow stump, which is actually a geyser named "Ol' Fateful". The ranger prepares to reward Humphrey with a dish full of cacciatore, but before Humphrey can take it, the geyser suddenly erupts, spouting the garbage everywhere, resulting in Humphrey having to start all over again at cleaning up the park.
