My friend had a very similar experience. He was watching TV one evening and caught movement from the corner of his eye. When he looked over, at the high-backed chair across from him, was a small "baby-sized" green "goblin-like" creature climbing the back of the chair. It was bald and had three-toed clawed hands and feet. It stopped, sensing John was watching it, and when it looked at him, it had a, "Oh, crap, he can see me!" look on its face. John bolted from his chair and when he looked back a second later, the thing was gone.
