World 1 (Puzzle & Dragons: Super Mario Bros. Edition)

World 1 is the first world in Puzzle & Dragons: Super Mario Bros. Edition. This world features typical grassy plains with many colorful hills, similar to New Super Mario Bros. 2 with Orbs scattered about the map. It consists of nine levels and a Toad House. The player starts the game with Small Mario and Small Luigi as Leaders, and Red Toad as a Helper. Larry Koopa is the boss of this world and is fought in his castle and airship.

World 1-4
After fighting the second set of enemies, the player will find a branching path. To reach the secret exit, the player must clear more Light Orbs than Fire Orbs. However, the course does not contain any Light Orbs, so the player will have to bring an ally that can create Light Orbs. Upon defeating the boss at the end of the secret path, the player will unlock World 1-5.
