Unlike most studios using CGI for bringing creatures to life, Jim Henson's Creature Shop was responsible for the creation of the Fazbear animatronics.
The animatronic characters were performed by puppeteers from Jim Henson's Creature Shop. For shots where the characters weren't moving, the puppeteers would control both the head and body movements. In the rare instances where a character would walk or dance, a stunt performer would don the costume while the puppeteers controlled the heads remotely.
