Super Mario Bros. 3/Items

Super Mushroom

 * Changes Mario into Super Mario. In this form, he can break bricks. Small Mario cannot.

Raccoon Leaf

 * Changes Mario into Raccoon Mario. In this form, he can fly, float, or wag a tail to beat an enemy.

Starman

 * Allows Mario to kill enemies simply by running through them. He will still lose a live, however, if he falls into a bottomless pit, runs out of time, or gets stuck in an auto-scrolling level.

Warp Whistle

 * Takes Mario to the Warp Zone, where he can get into a new world. Using it in World 1 will allow Mario to warp to World 2, 3, or 4. Using it in Worlds 2-6 will allow him to warp to World 5, 6, or 7. Using it in World 7 or the Warp Zone itself will allow him to warp to World 8.

P-wing

 * Makes Mario Raccoon Mario with a constantly-filled meter. The P-wing will last only one level, and then Mario will become regular Raccoon Mario. If he is hit by an enemy, he will become Super Mario.

Fire Flower

 * Changes Mario into Fire Mario. In this form, he can throw Fireballs. In World 6, Fire Mario can remove ice from iced coins and Munchers.

Anchor

 * Use it to keep an airship from moving across the map.

Music Box

 * Puts Hammer Brothers (or Piranha Plants in World 7) to sleep so Mario can get past them as if they weren't there.

Hammer

 * Allows Mario to break a rock. (Not to be confused with opening a lock, which can be done by defeating Boom Boom.)

Frog Suit

 * Changes Mario into Frog Mario. In this form, Mario can swim, which is useful for water levels; on dry land, he can jump higher than normal, but cannot run fast.

Jugem Cloud

 * Allows Mario to skip a level.
 * Note that If an airship hides where you can't reach it, you will have to complete the level to get to it.

Tanooki Suit

 * Changes Mario into Tanooki Mario. In this form, you can can do anything Raccoon Mario can do, as well as turn into a statue.

Hammer Suit

 * Changes Mario into Hammer Mario. In this form he can throw hammers, which are even stronger than fireballs, and the suit itself will protect him from fire attacks if he crouches down.

Kuribo's Shoe

 * Only available in World 5-3. In order to obtain it, Mario must hit the Goomba wearing it from underneath; any other attack destroys the shoe as well. While wearing it, Mario can jump higher than normal and stomp enemies that would otherwise hurt him on contact (such as Spinys and Piranha Plant), and he can still throw fireballs as well. If hit, he loses the shoe but not his powers; he automatically discards the shoe at the end of 5-3.
