Players control Mario, Luigi, Princess Peach, and Toad. Like in Super Mario Bros. 2, each character has its own unique abilities. Luigi can jump higher than other characters, Princess Peach can float in midair for a short time, and Toad can run fast. Rosalina also appears as a fifth playable character, who needs to be unlocked in order to play as her. She can use the spin attack move that is seen in Super Mario Galaxy and Super Mario Galaxy 2, but is the slowest character. There is a new item called the Super Bell that turns the player into their cat form, which allows players to climb up walls, run faster, perform unique attacks, and run up to the top of the goal pole at the end of each level. The game features a multiplayer mode.
