Clock

The Clock (マジカルクロック, Magical Clock) is a contact-activated object in The Legend of Zelda that can appear anywhere. If a clock appears and Link touches it, all of the enemies in the room will freeze in place, allowing them to be dispatched with ease. The clock does not affect enemies not on the screen, and once Link enters the next room, all enemies will unfreeze; moreover, the clock's effect does not have a time limit and will stay intact until Link leaves the room. Link does not get hurt even if he touches the frozen enemies.
