In this trailer for an upcoming documentary on Slothville, the world's only sloth sanctuary, the sleepy (but cute) animals seem determined to work their way inch-by-inch into your heart.

The trailer features a variety of the slow-moving mammals as they creep, crawl and move at a snail's pace around the facility, which is located in Costa Rica.

The documentary was made by filmmaker Lucy Cooke and premieres Saturday, Dec. 17 at 8pm EST on Animal Planet. Check out the irresistible trailer below.
