Spiketrap

The  is a type of obstacle in The Legend of Zelda series, first appearing in A Link to the Past.

Function
In most instances, Spiny Rolls move along a predetermined path at a predetermined speed, and serve to both impede progress and damage Link on contact. Some Spiny Rolls only need be dodged to get past them, but certain areas may require the usage of a jumping item to get over the traps in order to pass them safely.

Spiny Rolls beneath the Ikana well in Majora's Mask don't always bounce back and forth at the same speed, but do move in patterns that a player might have to judge in order to get past the group safely.

Only in Twilight Princess can players take the fight to a Spiny Roll by using the Dominion Rod on the resident statue in the Temple of Time, then using its hammer to smash the obstacles in one hit.

The Spiny Roll inside the Deku Tree in Ocarina of Time is unique in that it does not move along a path, only spinning in place above a pool of water. The puzzle in the room with the Spiny Roll requires going underneath it aboard a floating platform in order to pass through the room safely.
