“This is a Speed Flower! It temporarily speeds up time. You'll also earn triple points and coins while it's active!”
In-game text, Super Paper Mario

A Speed Flower is a type of flower found in Super Paper Mario. If one of the four heroes (Mario, Luigi, Bowser, Princess Peach) pick it up, everything will speed up for a short period of time. Within that time, points and coins the heroes would earn will be tripled. Mario's Flip Meter will also drain and refill faster. If an item that increases the player's points is used, the points will also be multiplied by six.

The Slow Flower is the blue-colored opposite of the Speed Flower: it makes everything go slower. If a hero grabs a Slow Flower while under the effects of a Speed Flower, the game reverts to normal.
