Conquer the Island was a medium difficulty stamp in Club Penguin. In order to obtain this stamp, the player had to conquer the island as a member of all four teams Club Penguin: Game Day!
This stamp was a bait item if the player attempted to perm it.
This stamp became unavailable, due to Nintendo no longer supporting Nintendo Wi-Fi Connection for Nintendo DS and Nintendo Wii systems, thus preventing stamps from being transferred from the game to online.
