The Sims 3: Island Paradise. Sims may encounter sharks on the surface or while they are diving in a dive spot. Sharks will only appear on lots that have a shark spawner. By default, only Isla Paradiso have pre-placed shark spawners, so players need to manually place shark spawners themselves. There are 4 types of shark in the game, which are the Blacktip Reef Shark, Tiger Shark, Lemon Shark, and Great White Shark.
When a Sim notices a newly spawned shark, they may wet themselves if their Scuba Diving skill is lower than 7. Sims can hide in an underwater cave to avoid sharks. There is a 5% chance that sharks may attack Sims, an additional +2% chance for each meat and fish inside the Sim's inventory, and an additional +20% chance if the Sim watches the sharks. When a shark attacks the Sim, the chance to win the fight is based on how many skill points the Sim has in Athletic, Martial Arts,[TS3:WA] and Scuba Diving skills. Having 0 of them will guarantee a loss while having 10 of each will guarantee a victory. If the Sim has Loves to Swim trait, there's a +30% chance they will win the fight.
If the Sim loses the fight, they will get "Mauled by Shark" and "Gasping for Air" moodlets. If the Sim is attacked while having either of these moodlets, they will die by shark attack and the ghost of the Sim will be purple. If the Sim wins against the shark, they will receive a shark tooth and get "Pumped" moodlet.
