World 1-2 (Puzzle & Dragons: Super Mario Bros. Edition)
From the Super Mario Wiki
World 1-2 is the second course of World 1 in Puzzle & Dragons: Super Mario Bros. Edition. It is a basic, underground level with enemies consisting of Goombas and Green Koopa Troopas. When the player enters this course for the first time, the game provides a tutorial of how to create teams and how to use Super Orbs. Clearing this course once unlocks Blue Toad as a Helper.
This level is straightforward, consisting of three battles with Goombas and Green Koopa Troopas, and a boss fight at the end with three Green Koopa Troopas. When playing this course for the first time, the Green Koopa Troopa at the center during the boss battle drops a Star Coin upon defeat.
The player has only Fire, Water, Wood, and Heart Orbs on the Orb field for this course.
