Just like previous Mario games, there is a tough Special World hidden in the game, in addition to its normal worlds. There are six standard Special World levels, and at least three more to unlock.
An entrance to each Special World level is hidden on the six standard worlds in Super Mario Bros. Wonder, as well as Petal Isles. In order to unlock them, you’ll often need to find secret exits.
