The skeleton in "Kubo and the Two Strings" was an over 15-foot-tall puppet.
It was created by Laika, a stop-motion animation house.
You can watch an exclusive behind-the-scenes video of how they built it below.
One of this year's best animated features, "Kubo and the Two Strings," shows a young boy, Kubo, go up against a larger-than-life skeleton nemesis in one scene.
While the skeleton may appear animated, he was actually built by hand as a working puppet for the film. And the skeleton wasn't just any puppet - he was a massive creation that stood well over 15 feet tall.

For comparison, Laika, the stop-motion animation house that worked on "Kubo," usually builds hand-made puppets which stand between six and 15 inches tall.
Universal Home Entertainment shared a behind-the-scenes clip with INSIDER showing how the giant stop-motion animation skeleton was brought to life.
Director and producer Travis Knight says the team applied the same principles they would to any of their other puppets, but just on a larger scale.

"This has a whole new set of different difficulties - access, physical space, weight. So it was really phyisically demanding," said animator Charles Greenfield. "A slow day would be eight frames a day in 12 hours ... A fast day? 18 frames."
Watch the clip below. "Kubo and the Two Strings" will be out on Blu-ray and DVD November 22.
