next world. There are six power-ups available in New Super Mario Bros.; the game allows the player to store an extra power-up when he is already using one, a feature carried over from Super Mario World. Three power-ups from Super Mario Bros. return in the game: the Super Mushroom makes Mario grow in size, the Fire Flower lets Mario throw fireballs, and the Starman makes Mario temporarily invincible. Three more power-ups are introduced in New Super Mario Bros.: the Blue Koopa Shell lets Mario withdraw into a shell to protect himself and perform a "shell dash" attack. He also swims faster when in this form. The Mega Mushroom grows Mario to an incredible size, where he can destroy everything in his path, and the Mini-Mushroom causes Mario to shrink, allowing him to enter tiny passageways. Mini Mario is so light that he can run on water and jump extremely high.

At the end of the first world, Bowser Jr. retreats to a castle, where his father, Bowser, awaits Mario on a bridge over a pit filled with lava. During a moment highly reminiscent of Super Mario Bros., Mario activates a button behind Bowser to defeat him,
