Top Ten Classic Examples of Nightmare Fuel from Nintendo 64 Games
Considering that this is my 64th Classic Examples of Nightmare Fuel list. It just seemed fitting...
Despite not being an actual hand Dead Hand is still terrifying just from its design as well as when battling the creature inside a tiny arena with countless hands that will try to grab you and unfortunately the only way to draw out Dead Hand is to let the hands grab a hold of you as it rises from the ground as it slowly moves towards you.

The creepiest area of the game and the music is just perfect for capturing the unsettling atmosphere.

Literally the first thing you see as you enter the main section of Clanker's Cavern is coming face to face with the giant mechanical whale Clanker with a creepy design that looks like getting ready to devour you.
Everything about this temple is creepy and unsettling especially when you realize the temple was basically used as a torture chamber by the Sheikah.


The Main boss of Gusty Gulch whose not only invincible but eats boos. literally the first time Mario meets Tubba Blubba while being hidden by Lady Bow he devours one of the boos that he was talking with and because he's invincible fighting him is suicidal since he obviously can't be hurt until after you enter the wind mill after stealing the key from his tower.
The Newcomers
The music and the setting just mash so well together as the seventh level of the game set in one of Gruntilda's creepy mansion where night has fallen as Banjo and Kazooie come across an organ playing ghost hand, a sleeping ghost which you had to avoid waking to obtain a jiggy, walking grave stones and even having to venture inside a toilet.
