How to plan a visit
Bring the Clefairy to access Rock Peak Dream Island. Each Dream Island resets one real-world day after your previous visit, so plan multi-island rotations across the week if you are racing the Sableye's Gem Hunt clock. Inside, head straight for the underground caves: every Red Crystal Cluster you break with Rock Smash drops four fragments, and this island sits at the high end.
