Fire Flower

When Mario or Luigi obtains a Fire Flower, they transform into Fiery Mario or Fiery Luigi. In this form, they can shoot fireballs which can defeat many enemies. The Flower first appeared in Super Mario Bros., which could be found in an ? Block if you had already obtained a Super Mushroom. In Super Mario 64 DS, a similar flower known as a Power Flower will give either Mario, Luigi, Wario or Yoshi a special power, which would originally be gained by wearing a special cap in Super Mario 64. When Mario uses a Power Flower, he is able to fly by doing a triple jump (same as Wing Cap). If Luigi uses one, he becomes partially immaterial and can move through certain objects to get to new places (same as Vanish Cap). If Wario uses one, he become metal and can walk at normal speed underwater and can withstand great winds (same as Metal Cap). When Yoshi uses a Power Flower, he is able to breathe fire (does not come from the original game).

In the Paper Mario series, when Mario and his allies are battling an enemy or two, this item does 3 damage to all foes.
