I am so excited about the chocobo! My ideas are as follows:

First idea, if possible there should be a rechargeable "boost" that accelerates giant yellow chickens at a geometrical/exponential rate. We should be able to catch air when we hit a hill at high speed. I don't want to be artificially stuck to the ground. It’s not realistic.

Customizable color (the more colors to choose from the better)

Ability to equip them with gear (if nothing else just for appearance)

Certain chocobo should be able to fly freely throughout the world (perhaps via a quest entitled "A chocobo gets its wings" or "Learn to fly")

I would like to see the terrestrial chocobo all transport at the same relative base speed (no one wants a slow chocobo). The aerial chocobo should be a faster means of transport. Both should possess the above boost function if possible.

I used to love racing my friends from nation to nation on chocobo. The rentals were all the same speed. To win the race required skill. It was fun. I would really like the "boost" function. Most of all I would really like a flying chocobo!
