In 2011, Imangi Studios released the single player endless runner game Temple Run for iOS devices. The game's scenario is simple: You are an explorer who has just stolen something from a temple and are now being chased around a narrow and winding path by demon monkeys.

After over a billion downloads across various platforms, the creators decided to expand the world by bringing a demon monkey to life—and who better to help with that than the creators at Jim Henson’s Creature Shop?

Imangi Studios recently posted a behind-the-scenes video on YouTube that shows how the costume was created using various sculpting, casting, and fabrication techniques. The finished product—which has a man inside—has already been used in a few ads, including the one below that shows what the monkey does when he isn't trying to catch thieves.
