Chocobo Feather

The Chocobo Feather (チョコボの尾, Chokobo no O) is a recurring, single-use item that is frequently used to cast Haste on a character.

Final Fantasy VII
The Chocofeather is an accessory that increases Dexterity by +10. It can be won once during disc 1 by winning all eight battles when looking for the Keystone or bought in Wutai.

Crisis Core -Final Fantasy VII-
The Chocobo Feather is a Key Item that adds the Chocobo summon to the Digital Mind Wave.

Final Fantasy X-2
The Chocobo Feather casts Haste on a single character.

Final Fantasy XI
Chocobo Feathers are sold at Chocobo Stables, and can be used for low-level arrow fletchings and other Clothcrafted goods. Much rarer are Black Chocobo Feathers, used in high level Clothcrafting.

Final Fantasy XII
The Chocobo Feather appears as loot that can be acquired from Chocobos. Four can be sold toward unlocking the Eye Openers at the Bazaar. A Chocobo Feather may be sold for 480 gil.

Dissidia Final Fantasy
The Chocobo Feather is not an item, but an accessory that has a 30% chance of breaking after battle, though it grants double EXP. Also in Destiny Odyssey VIII, Bartz gives Squall a Chocobo Feather for good luck. It later transforms into Bartz's crystal.

Non-Item Appearances
Choco Billy from Final Fantasy VII and Yu Hayakawa from Final Fantasy: Unlimited both wear Choco Feathers around their ears. In Final Fantasy VII, it serves no real purpose other than decoration, but in Final Fantasy: Unlimited, Yu uses the feather to communicate with his Chocobo, Chobi.

In Final Fantasy Tactics Advance, an Animist unit is holding an item similar to the Chocobo Feather at the Chocobo Rush ability.
