Spike

Spikes (スパイク, Supaiku) are metallic balls that float around posing potential threats to Link from within the Water Temple in Ocarina of Time. In several rooms, these enemies are triggered to release by switch causing several of them to flow out of a cage at a slow speed, obstructing an entire passage or endangering a room. These spikes can be subdued with a flick of the Hookshot where they retract into a more dense rock-like object; another hit from the hookshot is enough to destroy them. Although spikes are not the most dangerous of enemies in the Water Temple, they rank among the most aggravating.

Spikes are not to be confused with Blade Traps.

In Majora's Mask, objects that look identical to spikes can be seen suspended from chains in various places, mainly in Pirates' Fortress, Great Bay Temple, and Ikana Castle. They explode when they hit each other or Link.
