The Boxtrolls (2014) on Netflix

THE BOXTROLLS are a community of quirky, mischievous creatures who have lovingly raised an orphaned human boy named Eggs in the amazing cavernous home they've built beneath the streets of a city called Cheesebridge. The story is about a young orphaned boy raised by underground cave-dwelling trash collectors who tries to save his friends from an evil exterminator, the town's villain, Archibald Snatcher. When Snatcher comes up with a plot to get rid of the Boxtrolls. Eggs decides to venture above ground and "into the light," where he meets and teams up with fabulously feisty Winnie. Together, they devise a daring plan to save The BoxTrolls family. The film is based upon the children's novel 'Here Be Monsters' by Alan Snow.
