Muda Kingdom is the second level of Super Mario Land, and one of four kingdoms of Sarasa Land.

Muda is a water themed level. The first two stages are platformer levels that are slightly similar to most of the third stages on Super Mario Bros., and the third is an underwater level where Mario travels in his Marine Pop to fight enemies, at the end of which he must fight Dragonzamasu and his servant, Tamao.

Enemies found in Muda are Chibibos, Nokobons Honens, Pakkun Flowers, Mekabons, Gunions, Torions, Yurarins, and Yurarin Boos.
