World Star-Rainbow is the final Rainbow Course in New Super Mario Bros. 2, and is the Rainbow course featured in World Star. To complete this level, the timer must end with the two digits '99' (that is, 'x99', where 'x' can be any number) when the player reaches the Goal Pole of any World Star level. Once this level is completed, it can be completed again by rewarding the above condition once more.

The stage begins on a flat, green area with a star pattern in the background, a Pipe Cannon in the center of the level. Entering the Pipe Cannon causes few lines of coins to appear before the player is in the sky.
Mario is launched onto a moving platform. He encounters three star-shaped coin formations, then many 10 Coins and a giant coin fall toward Mario. He then passes a large Roulette Coin Block and a Red Ring, each forming star-shaped. Collecting all Red Coins restores the player's record with a Gold Flower. The level then ends with three more coin formations.
