World 3 introduces a lush, mountainous environment with waterfalls and caves, bringing new challenges like slippery surfaces, falling rocks, and the introduction of Bob-ombs. This world often requires precise platforming and careful timing, especially when dealing with enemies that explode or environmental hazards. The verticality of some stages can be quite demanding, making Luigi's high jump or Peach's float particularly useful. Explore thoroughly, as there are often hidden passages and valuable items tucked away in the nooks and crannies of these rocky landscapes. Be prepared for some tricky jumps and strategic enemy disposal.
