 In addition to the two times that the Beast appeared in the movie  (the face that appeared in the closet and the creature that guarded  the kids door), the script had it appearing during the scene where  the family and investigators are looking at the tape of the  manifestation. The giant ghost that they saw visually slowly  resolved itself into the image of a face of a cruel old man: the man  we know in the later films as Reverend Henry Kane.
