Oh, and you know what else? King Jingaling's throne room in Banjo-Tooie, once Grunty sucked the life out of him. I liked the song (
"In the Hall of the Zombie King"), but boy was I terrified to go in there. My friend and I would play it together and see how close we could get to Jingaling without freaking out or getting attacked.
In that same game, Grunty Industries. Inside the building, there were these security cameras, and if one saw you, it would release these horrible things to attack! I pretty much avoided the whole level until my friend and I snuck up on one of the cameras and destroyed it. I still panicked whenever I entered a room with one, though.
