And you think your family's full of squares? Check out this first teaser trailer for "The Boxtrolls," an animated film based on a popular Alan Snow kids' book called "Here Be Monsters."

As you can see, this 3D stop-motioner is about a rather non-traditional family: a boy and some tunnel-dwelling boxes.

Yep, as the narrator explains so eloquently, "Sometimes there's a mother. Sometimes there's a father. Sometimes there's a father and a father.* Sometimes both fathers are mothers. Sometimes there's a mother, father, grandmother, grandfather, weird aunties with funny hats, a butler and old uncles who do nothing but eat rare, smelly cheeses. And sometimes, there's no one at all. But sometimes, there are boxes. Families come in all shapes and sizes, even rectangles."

The story follows a little orphan boy named Eggs (Isaac Hempstead-Wright) who's raised underground by these creatures ("cave-dwelling trash collectors"), and the lot are notorious around Cheesebridge for being fouler than foul, even if it's not true. Soon, they become targeted by the town exterminator (Ben Kingsley), so it'll be up to young Eggs to save his little cardboard family.

"The Boxtrolls" is another animated feature from Portland's Laika Entertainment, which is quickly becoming known for this sorta kooky animated fare thanks to "Corpse Bride," "Coraline" and last year's "ParaNorman."

The film, which hits theaters on Sept. 26, 2014, also features the voicework of Elle Fanning, Simon Pegg, Toni Collette, Jared Harris, Tracy Morgan and Nick Frost.

The first poster for "The Boxtrolls" is also in.

*This tidbit has earned the filmmakers a bit of attention for being progressive, but Laika CEO Travis Knight insisted to The Hollywood Reporter, "We’re not in any way trying to be activists. We’re just trying to be who we are. All art and all artists have a point of view, a way of looking at the world. We want to make films that are bold and distinctive and enduring and actually have something meaningful to say."
