They can also befriend local chimps on the island and marry other Sims. The user finds many 'books' along the way that give him or her various quests to follow to complete the game. Also, the player can repair a broken ceremonial forge on Volcano Island that will cause a fourth island, Crystal Island, to rise out of the sea. They can either build a boat or travel to the volcano's summit and use the radio parts to send an SOS to a nearby ship. The player has the chance to return to civilization on this island. On Volcano Island, the player will discover the remains of the llama people. A third island, Volcano Island, can be reached once the player finds the second beach on Airplane Island and builds a canoe. While exploring Airplane Island, the player will find radio parts that are crucial to completing a goal later in the game. The player then has the option to form a tribe of Sims if the relationship level is high enough. After arriving on the island, the Sim is reunited with some of his/her lost crew during the player's exploration of the island. Shortly after exploring Shipwreck Island, the Sim discovers a second island, Airplane Island, and builds a raft to reach the new location.

The Sim finds books detailing the goals the Sim must follow to survive on the islands and escape. The player's starting Sim wakes up on First Beach, Shipwreck Island. After the crew's creation, a slide-show starts of some mobile phone pictures that are taken showing the trip and also showing the storm that wrecks the ship. The game begins on a boat (named Simplicity) after the player creates a crew.
