In the Bag (1956)

The tourists have left behind lots of trash. Ranger Woodlore enlists his bears to clean up by turning the task into a game (and a dance), but when he takes to his hammock, they see through his ruse. Plan B: bribery no food until cleanup complete. But all the other bears put their trash in to Humphrey's section, so he resorts to a number of unsuccessful ruses to dispose of it

Unfortunately the movie In the Bag is not yet available on HBO Max.
