Pinnacle Rock

Pinnacle Rock is a location in Majora's Mask, and is placed within the Great Bay Coast, full of mist and signs of warning found on the sea bottom.

Features
Beyond the signs, Pinnacle Rock houses the lair of the Sea Snakes, which consists of a deep hole in the sea filled with predators, all of them serpents. There are eight sea snakes within, and three of them have the Zora Eggs that Mikau had been frantically searching for. Two of the serpents have chests containing 20 Rupees, one with a lost Seahorse, and the two remaining have nothing.

The easiest way for Link to get through the murky waters of Pinnacle Rock is by using the help of the friendly seahorse located inside the Fisherman's Hut. Once Link has given the Fisherman a pictograph of a Gerudo Pirate, he receives the seahorse in a bottle. The aquatic being wishes to go to Pinnacle Rock, so after it is dropped near the entrance, the seahorse guides Link to the inner part of the serpent-infested sea. There, he explains to the young hero that his friend has been trapped by a sea snake, and asks Link for his help. While Link makes his way to the bottom of Pinnacle Rock trying to find the three Zora Eggs, it is recommended that he defeats each of the sea snakes he encounters along the way, for the only way to save the seahorse is to defeat each of the serpents within. The two seahorses will reward Link with a Piece of Heart once they are reunited.

However, it is possible to get through Pinnacle Rock without the seahorse's assistance. The way to do so is:
 * Stop at the first sign, go to the second one on the right, go one forward, head to the left until another sign comes into sight, one up, one right and then into the lair.

Getting out this same way is quite difficult. It is far easier for Link to simply swim out a random way and magically wind up back at the entrance to Pinnacle Rock.

Other Appearances

 * In Animal Crossing, when Gulliver is talking about his past journeys, he mentions the sea snakes, for he says: "Or when I fought the sea snakes at Pinnacle Rock! Wait a minute... That wasn't me!"
