Hammer Suit

"Hey you! How about lending me your clothes? No dice!? What a drag!"

The Hammer Suit (alternatively Hammer Bros. Suit,  Hammer Brothers Suit, or Hammer Brother Suit ) is an item found in Super Mario Bros. 3 and its SNES and Gameboy Advance remakes. This item transforms Mario or Luigi into Hammer Mario or Hammer Luigi, which gives them the ability to throw hammers. Super Mario Advance 4: Super Mario Bros. 3 adds a new utility to this suit: its hammers can break Gray Brick Blocks.

Super Mario Bros. 3
Hammers thrown by Hammer Mario or Hammer Luigi can defeat almost everything, including Bowser, but as with other power-ups, one hit from an enemy causes them to lose their power. The characters also gain a fireball-proof shell when ducking, but lose their ability to slide down hills. If Mario or Luigi ducks while in the Hammer Suit, they resemble a Buzzy Beetle.

In the original Super Mario Bros. 3, retrieving a Hammer Suit will make Mario and Luigi's skin turn a darker, yellowish tone, while no other power-ups in the game do so. It is unknown what purpose this skin color change has, but it is possible that Nintendo placed the odd effect in to make the textures of Mario and Luigi's skin bear more resemblance to that of the Koopa Troopas and Hammer Brothers themselves. On the map screen and in remakes, Mario and Luigi's skin colors stay the same when they wear the suit.

The Adventures of Super Mario Bros. 3
The Adventures of Super Mario Bros. 3 episode "Reptiles in the Rose Garden" is the only episode to feature the Hammer Suits. Mario and Luigi use them to sneak aboard and hijack King Koopa's Doom Ship so they could use the Levitation Beam to warp the White House back to Washington, D.C.. Although they did not use the Hammer Powers that came with the suit, they attempted to use the suits to trick a group of Sledge Brothers into thinking they were one of them, although the disguise failed to trick the enemy.

Trivia

 * The Hammer Suit (as well as Hammer Mario) is not mentioned in the original NES or All-Stars versions' instruction booklets. The Virtual Console re-release's Operations Guide, which is based on them, also has no reference to it. In the original game, it is something of a "secret" powerup, as it only shows up in hidden areas and randomly from Toad Houses, though in later versions, it is made to consistently appear in certain Toad Houses.
