The Muda Kingdom is an aquatic-themed world, featuring many underwater sections and enemies. You'll encounter new foes like the Piranha Plant-like enemies and more challenging platforming sequences. The water levels often slow Mario's movement, requiring careful navigation. Be prepared for more precise jumps and strategic use of your Superball Flower, as it can be very effective against enemies in tight spaces. This world also introduces more hidden areas and secrets, so keep an eye out for suspicious blocks or pathways.
This kingdom consists of three standard stages and a boss battle against Dragonzamasu. The environment is characterized by water, coral, and ancient ruins submerged beneath the waves. Some stages will have you swimming, while others will be on land with water hazards.
