Squid-Hunt

is a minigame in.

Location and Rules
The Squid-Hunt minigame is found inside the lighthouse on Windfall Island and is run by Salvatore. During the game, Link must find and destroy three randomly hidden squids in the 8×8 grid with only 24 cannonballs. The squids are two, three, and four squares in length and only reveal their locations upon bombing the squares in which they are hidden.

The first time Link finds all three squids, he is rewarded with a Piece of Heart. A second victory yields Treasure Chart 7. Every subsequent victory provides a Purple Rupee. If Link can locate all three squids using less than 20 shots, he will also be rewarded with Treasure Chart 23. After Link has obtained both Treasure Charts, he will receive an Orange Rupee every time he beats his personal record.

Trivia

 * Several Yellow Rupees can be found behind the ship seen in the background of the grid.
 * In the Japanese version, the game's goal is to sink ships rather than squid.
