Bongo Bongo is probably the creepiest thing in that game...he sure scared the crap out of me when I first encountered him. What's interesting to speculate about is the origin behind the creature; I've read a lot of theories that he was originally a man executed in ancient times, hence the severed hands and lack of a head.
yeah he is creepy, He is the ghost of a man who had his hands chopped off and beheaded. Probably using demon magic powers, res-erecting the dead (redeads). His house was where the well is. In the bottom of the well is like a bloody basement of a serial killer. That music was so creepy first time i went down there.
