Treasure Hunt

 was a 2-player game that could only be accessed in the Captain's Quarters of Rockhopper's ship, The Migrator. Because of this, the game could only be played during parties when the ship was docked, at the Beach.

Gameplay
Two players worked together to uncover treasure in the 10x10 sandbox. One player could uncover rows, while the other could uncover columns. The players alternated over 6 turns to uncover a row or column each, for a total of 12 turns.

Regular

 * Coins were worth 1 coin.
 * Rubies were worth 25 coins.
 * Emeralds were worth 100 coins each. Only one emerald appeared in the sandbox and did not appear in every game.

Holiday Edition

 * Peppermints were worth 1 coin.
 * Candy canes were worth 25 coins.
 * Ornaments (or baubles) were worth 100 coins each. Only one ornament appeared in the sandbox and did not appear in every game.

Tips

 * Sparkles in the sand gave clues as to where treasure was buried.
 * Two sparkles next to each other were either hiding a ruby or a candy cane, which were larger and worth more coins than coins and peppermints.

Trivia

 * A variant game of Treasure Hunt was Dino Dig.
 * Unlike most of the other games, you would not receive double the amount of coins you earned even if you collected all the Treasure Hunt stamps.
 * It was possible to get all the stamps in one Treasure Hunt game.

Christmas Edition
During the Holiday Party 2018 and 2019 when The Migrator visited the island, it was decorated for Christmas. The Treasure Hunt was changed for the season. Coins were replaced with peppermints, rubies were replaced with candy canes, and emeralds were replaced with ornaments. The sand was changed into snow in this edition, since it was colored white.
