As this new trailer for The Boxtrolls shows, the movie’s titular trolls aren’t the likeliest of superheroes. They live underground, feast on grubs and probably use Ghostbuster II’s slime river for bath times.

The Boxtrolls is the third feature-length effort from those stop-motion whizzes at Laika.
