World Star is the final world that appears in New Super Mario Bros. 2. It has nine levels and a 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 blocked by another sign that requires nine Star Coins to remove it. 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 and also permanently brings back all Toad Houses in the game.
