World Star (New Super Mario Bros. 2)

World Star is the final world that appears in New Super Mario Bros. 2. It has nine levels and a hidden Toad House. Of the levels, there is seven numbered levels, a castle and a rainbow level. Blocking the levels in the world is a Star Coin Sign, which requires 90 Star Coins in order to open the path. Also at the beginning of the world is a Toad House, which will appear after all Star Coins have been found. It is blocked by another sign that requires nine Star Coins to remove it, and it gives the player a Super Star for their item slot. Dry Bowser is the boss of the castle. The world is unlocked after defeating Bowser, unlike all other special worlds, which are unlocked via cannons. Unlike the first eight worlds, the levels of World Star have Moon Coins, instead of Star Coins. World Star appears to be similar to World 9 and World S, as they are all bonus worlds unlocked by beating the final boss.

Collecting all Moon Coins in this world adds a star to the player's file. Finding all Moon and Star Coins without using White Raccoon Mario results in the Toad Houses permanently staying in their position without disappearing.
