Vacuum Mouth

The Vacuum (近付けないトラップ, lit. "Vacuum Mouth") is a strange and rare 'enemy' featured in Link's Awakening. It is immobile and essentially non-aggressive; it's ability is to attract all creatures (both Link and enemies alike) inexorably towards it. It does so in short five-second bursts accompanied by a whooshing noise. The Vacuum first appears in the Bottle Grotto, in a room along with three Keese. The Keese will be sucked into the Vacuum, and Link must cross the room while avoiding the same fate.

Another version of the Vacuum exists which has the exact opposite ability; it expels air, preventing Link from being able to approach. This reverse-Vacuum, found in Key Cavern in the room immediately to the right of the entrance, can only be defeated by charging it using the Pegasus Boots.
