- The (aptly named) "Cave of Bad Dreams" is spooky enough to begin with. You eventually have to escape Jano, a legless, one-eyed monster that intends to eat you. This is done by sliding down an obstacle filled course while the camera is framed by the monster's drooling teeth following you (photo).
- The dark holes with nothing but glowing eyes and a spindly hand reaching out for Rayman in said level. If he gets caught, you get to watch him be slowly strangled and pulled into the hole to die.
- Oh, and... that "Mini-Jano" you encounter halfway through the level and in The Sanctuary of Stone and Fire? He will eat you alive if you get too close, respawning you at the last checkpoint.
- The giant spider you face at the beginning of the Canopy level has no doubt scared some players. The music that accompanies that part of the level doesn't help matters, either.
- The Zombie Chickens.
- Piranhas that look much more creepy than in the first game. Most of their body is a huge mouth, studded with long and sharp teeth. Their design is a bit like the langoliers from the novel of the same name by Stephen king.
- The way Foutch sneaks up on Rayman and slugs him so forcefully he loses one of his "permanent" powers: flying. Yes, he hits Rayman so hard that Rayman forgets how to/is unable to fly! Damn.Rayman: (as he's sent falling) I can't fly anymore!
- Eig in the Dreamcast and PS2 versions, a horrific monster that appears in the Marshes of Awakening, but only makes a split second appearance. Way later, in the Sanctuary of Rock and Lava, he appears out of the water next to a secluded log. If Rayman approaches him, he'll eat him alive.
- The giant mechanical dinosaur that guards the Iron Mountains is surprisingly fast for its size, something most players find out as they speed away from it on their walking shells, only to get trampled and killed instantly.
- The music in the Tomb of the Ancients — especially the "Psycho" Strings bits — is creepy on both the N64 and Dreamcast versions, but the Dreamcast version is just unnerving.
