Super Mario Bros. 3/Items

Super Mushroom

 * Changes Mario into Super Mario, who can break bricks. Small Mario cannot.

Raccoon Leaf

 * Changes Mario into Raccoon Mario, who 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. This P-wing will last only one level, and then Mario will become regular Raccoon Mario.

Fire Flower

 * Changes Mario into Fire Mario, who can throw Fireballs. In World 6, Fire Mario can remove ice from iced coins.

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, which is useful for water levels.

Jugem Cloud

 * Allows Mario to skip a level.

Tanooki Suit

 * Changes Mario into Tanooki Mario, which can do anything Raccoon Mario can do, as well as turn into a statue!

Hammer Suit

 * Changes Mario into Hammer Mario, which can throw hammers, which are even stronger than fireballs.
