Ice Ring Isle
From Zelda Wiki.org
The Ice Ring Isle is an island in The Wind Waker where the Iron Boots are located. The Fire Arrows are needed to unfreeze the Freezard-looking facade upon the island in order to set foot on its cold surfaces without freezing. Upon melting the ice upon the facade, Link will have a 5 minutes to complete the island's challenge before it freezes itself again. After jumping from ice block to ice block, and skittering across a narrow strip of ice, Link will drop into a cave within the rocky facade of the isle. Link must then traverse two slippery slides before achieving the isle's prize, the Iron Boots.Upon receiving the Iron Boots, the 5-minute timer will stop, and Link can forever traverse the Ice Ring Isle at his leisure.
Within the main cavern and after getting the Iron Boots, a small cavern located nearby opens and Link, upon dropping in, will find a cryogenic cavern filled with enemies, rupees and a Piece of Heart.
