Loopy Lights is the fourth level in the sixth world named Chimp Caverns which is in the SNES title Donkey Kong Country and is also the thirty-second level in the game. The level contains 2 bonus rooms. What makes this level unique, is that during the level the lights will become very dim unless you touch an "On" barrel which are spread throughout the level. In the dim lighting, the only visible part of an enemy is there eyes, so you aren't completely defenseless as seen in Blackout Basement, also a level in DKC where lights turn on and off.
There is a level before Loopy Lights named Necky Nutmare, but the level is exclusive to the Gameboy Color version only.
