World 6-Castle (Puzzle & Dragons: Super Mario Bros. Edition)

 is the thirteenth course of World 6 in Puzzle & Dragons: Super Mario Bros. Edition. It is a castle level with enemies consisting of Chain Chomps, Bony Beetles, a Big Thwomp, a Big Bony Beetle, a Big Whomp and a boss fight with Roy Koopa.

Layout
This level is straightforward, consisting of six battles (the sixth battle having a Big Whomp) and Roy Koopa for the boss fight (if the player already has Roy as an ally by clearing, they fight Double Lakitu instead). Roy Koopa has an extremely high amount of defense: to defeat him, the player must either create a large Combo attack to penetrate his defenses or bring an ally whose Skill allows them to lower the defense of enemies (such as a Bullet Bill's or its evolutions, the Banzai Bill and King Bill).

The player has all five elemental Orb types on the Orb field, while Heart Orbs are disabled.
