Do mystery islands have rare fish?
Do mystery islands have rare fish? Mystery tours provide the player with a way to gather more crafting materials, such as iron nuggets if they run out of them on their home island, as well as opportunities to collect rare fish and bugs, non-native fruit trees, and hybrid flowers.
Do mystery islands have better fish?
Mystery Islands have higher fish spawns than your island. Though the layout is random - some could have a river cliff, while others will only spawn trash for you to catch - it can help you better catch fish in certain locations, especially if you use the 'scaring' tactic mentioned earlier.
Will villagers appear on mystery islands if your island is full?
If you have a free plot of land on your island, then a randomly selected villager will appear on any Mystery Island you visit. They will continue to appear, until this plot is sold and, if you have no land for sale, then every Mystery Island you visit will be uninhabited.
