World 3 (Puzzle & Dragons: Super Mario Bros. Edition)

World 3 is the third world in Puzzle & Dragons: Super Mario Bros. Edition. This world takes place in a desert. Orbs are scattered about the map, and there is a large sinkhole in the second half of the world. This world consists of ten levels and a Toad House. Morton Koopa Jr. is the boss of this world and is fought in his castle and airship. The world's theme is a remix of the theme from World 2 of New Super Mario Bros. Wii. Clearing unlocks Fire Mario and Fire Luigi as Leaders, and clearing  unlocks the Lucky ? Blocks section in Toad Houses.

A more difficult version of World 3 exists as a Special World: ★World 3.

To reach the secret exit in this stage, the player needs to enter the purple Warp Pipe at the split path, which can be found after the second set of enemies in the stage. In order to enter the pipe, the player needs to clear more Dark Orbs than Water Orbs. However, since the course does not have Dark Orbs in it, the player must bring an ally that can create Dark Orbs. Upon entering the pipe and defeating the boss at the end, the player will unlock.
