Rabbit Beams are enemy traps found in A Link to the Past.
Rabbit Beams are traps that first appear within Skull Woods. Usually found underneath certain pots or large rocks, these beams consist of five revolving stars. They will chase after Link and if they come into contact with him, they will temporarily disable the effects of the Moon Pearl, transforming Link back into Bunny Link.
Link is defenseless while he is in his Bunny Form. If Link is hurt while in Bunny form, he will immediately revert to his normal form, otherwise he will return to normal after five seconds.
Despite seeming invincible, Link can defeat a Rabbit Beam with any of the three Magic Medallions.
