Hookshot
The Hookshot is one of the items that Link must acquire in Ocarina of Time, given to him by the deceased Dampé the Gravekeeper. It is the prize if Link wins a race that Dampé challenges him to. He found it while digging for treasure in his graveyard. The Hookshot can be used to help Link from one place to another, as long as the place the Hookshot "hooks" onto is wooden. It can attach to trees, boxes, logs, etc. It can also make enemies stop still in their tracks, leaving them open to repeated attacks. Link will need to use the Hookshot to get himself past many obstacles, until he acquires the even better Longshot.
The Hookshot can also be found in The Wind Waker. It is found in the Wind Temple and used to defeat Molgera, Protector of the Seal
The Hookshot is also found in A Link to the Past. It is located in a temple in the Dark World.
The Hookshot is also found in Link's Awakening. It is located in Level 5: Catfish's Maw.
