Power Flower

Power Flowers are power-ups found in Super Mario 64 DS. They have the appearance of flowers with green stems, red petals, and a yellow center with a face. When collected, they give the player a power-up depending on what character you are playing as. Power Flowers are unlocked in Tower of the Wing Cap, which is labeled ? Switch in Super Mario 64 DS. A list of the power-ups given by the Power Flower includes:


 * Yoshi: Yoshi obtains fire breath that can burn ice and enemies.
 * Mario: Mario turns into a balloon that can fly around, similarly to the P Balloon from Super Mario World.
 * Luigi: Luigi obtains the abilities of the Vanish Cap.
 * Wario: Wario obtains the abilities of the Metal Cap.

Super Mario 64 Manifestation
In some personalized copies, the Power Flower can appear in the original Super Mario 64. It can appear in any of the 4 ! box types, replacing the cap or object inside of the box. It can give the player 1 of the 3 cap abilities upon being collected. This can also apply to anomalous power-ups, such as the Fire Flower. In personalized copies that have multiple playable characters, there will usually be no difference in the Power Flower's behavior.

Unused Wing Cap Power Flower
If Parameter1 for the Power Flower is set to 1, it gives the player the Wing Cap ability. This was likely Mario's original ability before he was given the P Balloon. This is never used in game, but in some personalized copies, it can occur, sometimes even alongside the feather object.

Object Replacement
In some personalized copies of Super Mario 64 DS, the Power Flower is replaced with the original caps, allowing any character to use the abilities. Notably, Yoshi's fire breath ability can reportedly be replaced with the Fire Flower. Mario's ability can also be replaced with the P Balloon, which usually glitches out other character models as Mario is the only one with a specific model for this, usually resulting in the player character distorting or T-posing. Notably, the Speedy Shoes from Wow! Waluigi have also been reported alongside playable Waluigi, likely an object equivalent of his warpspeed ability mentioned in the Purple Prizes magazine.

Trivia

 * Due to the Power Flower giving Luigi and Wario the Vanish Cap and Metal Cap abilities, the levels corresponding to those caps no longer have cap switches, instead being regular special levels.
 * The Wing Cap is one of the only power-ups in Super Mario 64 DS that isn't obtained from the Power Flower, the other being the Mushroom, instead being obtained from a feather.
 * The Power Flower appears somewhat similar to the unused Dancing Flowers effect in Super Mario 64.
