On May 25, 1985, the Littles starred in their first animated feature which serves as a prequel to the television series. "Here Come the Littles" follows a boy named Henry Bigg as he meets a family of miniature people that lives in his home. While his abusive uncle Augustus plans to build a shopping center at the site of his home, Henry teams up with the Littles to prevent this scheme.
The Littles visit a blind elderly woman and help her out. They come across the journal of her late husband, which tells that he hid $50,000 cash in order to help out his wife. Unfortunately, the old lady's landlord gets hold of the journal, and seeks to claim the money for himself. The Littles must work to thwart the landlord and get the blind woman her rightful inheritance.
Dinky wins a contest for a gasoline-powered model airplane, and is required to come to the model company's office in a huge city to pick up the contest prize. Since Dinky is a Little and risks exposing himself, Henry offers to help claim the prize, since he is in the city visiting relatives at the moment.
Grandpa, Dinky, Tom, Lucy and the Little Scouts are out camping in the forest. Their trip becomes urgent when an Air Force pilot had been forced to eject and is found unconscious in the woods. Grandpa warns the man could die if left untreated for too long, and the Littles must figure out a way to alert men of the downed pilot's situation without revealing themselves.
As a result of Dr. Hunter redoubling his efforts, the mayor of the Littles prohibits the Littles from going to the surface. This does not sit well with Little society, and the mayor's approval rating takes a hit. Meanwhile, a Little named Smilin' Al visits the community, traveling the world with his pet dog. Smiling Al takes advantage of the mayor's unpopularity to unseat him in the upcoming election, promising no restrictions on Little travel.
