Haunted Tomb is a realm connected to the Midnight Mountain, strongly based on ancient Egypt.
- Christine (On a ledge)
- Will (Guess "Egg" in the riddle)
- Malcom (At the end of the slide)
- MJ (Defeat four Rhynocs at the Demolition Competition)
- TJ (Defeat another ten Rhynocs at the Demolition Competition)
- Roxy (As Agent 9; defeat all enemies that King Rover has sent)
- MJ's name might be a reference to the deceased legendary pop star Michael Jackson, whose name was commonly shortened as MJ.
- This level was originally called Catacomb Caverns.
- In the PAL and non-greatest hits versions of the game, the realm shares its theme with Cloud Spires.
- The Agent 9 area can be accessed quickly and without rescuing him only with action replay with the moon jump.
- Sometimes, the Scarab Beetles will walk in thin air, as if there is a platform there.
- There is a reference to Crash Bandicoot in this level. When one of the dogs asks you a riddle, one of the answers you can give is "bandicoot."
