Deku Flower

The Deku Flower appears in Majora's Mask. It can be only used while wearing the Deku Mask, and allows Deku Link to fly around using two flower-helicopters. This effect is only temporary; after some time Deku Link stalls and falls.

There are two different types of Deku Flowers; pink (the normal) and yellow. Yellow flowers allow Link to go further and higher than the pink, and are inhabited by Business Scrubs. The Deku Flower plays a important role in various Temples (especially the Woodfall Temple) and is used in-game to reach places that often hold items such as heart pieces.

It is also very important in the Deku Scrub Playground which is an entire mini-game that uses the Deku Flower to get from platform to platform.

Deku Flowers also appear in Ocarina of Time, but they serve no purpose except for places Deku Scrubs can hide if Link gets too close to them.

Trivia

 * The Boko Bud serve a similar function for Link when he has the Deku Leaf.
